Ubuntu Multimedia :: MythTV - Poor Flash / No Gnome

Mar 28, 2010

I am working on a Mythtv frontend/backend/desktop and am at a loss. The goal is to use myth to record programming from the free broadcasts (i fired the cable) and the desktop to watch flash video of the shows that aren't on the broadcast networks...like TNT, natgeo or the comedy channel. Software is Mythbuntu 9.04 running nvidia 180 drivers

I imagine the hardware is adequate, it is well above minimum specs that I can find.
AMD Athlon 3000+ processor
2gigs of PC2700 memory
Gforce 6200LE 512MB DDR2 video card AGP
Hauppage HVR-1600 tv card PCI

I have two problems, well three now if you count the crashing firefox. Myth TV is working fine. There was a conflict with the video card and the tv card. But now when I try to view flash video it is jittery...Firefox has started crashing now and that is a new thing. It will allow me to start a video and the the window will just close with no warning. I tried a local radio stations website and it did the same thing. When I connected to pandora it worked but I could only get the songs to play for around 30 seconds before it would skip to the next one.

I wanted to have the Gnome desktop instead of XFCE but nothing I do seems to change it. With that explanation in mind:
Is this hardware enough for what I want to do?
Is loading Mythtv first then adding gnome the best solution? (if not, I think I can redo the Mythtv setup and conflict resolution again without cracking up).

Ubuntu Multimedia :: Poor Sound In Fullscreen Flash Video Lenovo T60?

Jan 12, 2011

Sound is fine in flash video, but gets garbled in fullscreen.

Another problem I'm having is that when I turn the volume past 60% using the sound applet on the panel, it gets very distorted. If I open sound preferences, I notice it is in the "amplified" zone at this point, so I have to keep it in the "unamplified" zone, but then it's not loud enough.

Here is my soundcard info:

00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio C
ontroller (rev 02)
Subsystem: Lenovo ThinkPad T60/R60 series

[Code].....

Ubuntu Multimedia :: Play Anything - Music - Flash - Videos - Games - 'muffled' - Poor Sound Quality

Apr 7, 2010

I just got my hands on an MSI E7235-295US and slapped Ubuntu 9.10 on it. So far everything's worked great, but I am beginning to get a bit concerned about my sound quality. The laptop itself has 5 speakers + subwoofer so I should be getting 5.1 sound, if I understand things correctly (the newegg link should provide more details) and when I play anything (music, flash, videos, games, etc...) the sound comes out 'muffled'. Almost as if it is in a concert hall, maybe. I initially wondered if the problem is related to the 5 speakers and if the sound is initially only setup for two. If that is the case, nothing I've done has seemed to made any real difference. I've tried changing the master/pci channels, but it only hides it a little, and doesn't solve the problem.

This seemed to be on the right track, but the laptop is still really new and not listed in the alsa file.

Some info:
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
Subsystem: Micro-Star International Co., Ltd. Device 7220
Flags: bus master, fast devsel, latency 0, IRQ 22

Ubuntu / Apple :: Poor Responsiveness In Flash Drive Installation

May 13, 2010

I installed Ubuntu 10.04 on an 8GB flash drive, and through much effort, was able to boot it on my white MacBook (2Ghz Core 2 Duo, 2GB RAM). I find that responsiveness is really poor, for example, the display frequently freezes when I switch windows, or load a web page. Is this expected for Ubuntu that's running from a flash drive? Are there ways to improve this?

Ubuntu Multimedia :: No TV In MythTV Frontend?

Feb 11, 2011

After overcomming a lot of difficulties, my MythTV (Via Epia 10000EG with Hauppauge PVR 500 card) worked with Mythbuntu 9.04. Last year it crashed and I had no time to spare to rebuild it.

Last couple of weeks I had more time and downloaded and tried to install Mythbuntu 10.10. Everything seems to be installed ok, but I get no picture in MythTV when I select "Watch TV" and no picture when I try to record something. When watching TV, the message "Please wait" appears for appr. 5 secs and then the system returns to the menu.

I installed Mythbuntu 10.10 and am using the provided IVTV drivers.

Dmesg and lspci give no errors, every seems to be in order, IVTV drivers are loaded, initialized and errorfree. Cat /dev/video0 gives me static in MPLAYER. The MythTV backendlog doesn't even give a message, the frontend log just says there is no picture...

There seems to be an error between the back and frontend. I checked the settings in capturecards, TV sources, channel edits, etc,etc, but I can't find it.

Ubuntu Multimedia :: MythTV So Hard To Configure?

Jan 9, 2010

I've been at this for the last hour. I just put a Hauppage WinTV-TVR-1800 into my machine, rebooted and installed MythTV. I set up the card, the video source and the input as well as configured a few random channels. I click WATCH TV in the menu, it goes to a screen saying, "Please Wait....", then it brings me back to the menu. There's no error, is there some sort of log file.

Here it is run in the terminal:

Code:

Ubuntu Multimedia :: Unable To Get Sound In MythTV?

Jan 22, 2010

MB: Gigabyte 790XTA-UD4 boards, with internal sound
4Gig Mem, Phenom II CPU, 1 TB HD
HD in: 2 pc5500 TV cards
HD Out: GeForce GT240 out,

I'm getting very frustrated, having dropped a substantial (for me) amount of money trying to get a DVR setup, and Myth TV has punished me every step of the way.At this point, the extreme frustration is that sound *was* working earlier - not going to the TV via HDMI (Which seems like it should be easy but I've yet to get it to work) but I had speakers working - right up to the instant I installed restricted extra's to run mp3's - the instant I got totem to play sound, I completely lost all sound from myth TV, even playing back digital files it has recorded have no sound now.

alsamixer seems to have been used numerous times to fix these issues, but doesn't actually show as a valid package when I check the repository - I installed the gnome version instead, but nothing I do there seems to have any effect.I'm not entirely sure if I need/should be using the patch from the pc5500 cards into the sound card line in - as near as I can tell, that's only for analog signals, and it *was* running happily without it.

As mentioned - sound is fine from everything else, but even playing a recorded file I have no sound playback (Note: I had not recorded anything I can verify *had* sound before). I've gone through various guides, and I got nuthin'. All the actual cards and hardware have every appearance of working.

Ubuntu Multimedia :: Viable Alternatives To Mythtv?

May 8, 2010

Are there any viable alternatives to mythtv? I find the setup to be very cumbersome and the keyboard interface is a poor second to Windows Media Player for a basic PVR system on a desktop computer.

Mythtv seems an overkill for what I require, just to simply watch TV using my DVB-T input and record shows when I'm away from home.

Ubuntu Multimedia :: How To Disable OpenGL MythTV

Aug 3, 2010

I was configuring mythtv and when I was in the video settings I set it up to use OpenGL. Now I can no longer see video and I can't get back to the settings screen to disable OpenGL. Is there a config file that I can edit to disable OpenGL or someway to revert everything back to default. I tried completely removing the frontend and reinstalling it but that didn't do anything.

Ubuntu Multimedia :: Upgrade To 10.10 = No Sound In Mythtv?

Oct 13, 2010

that said on to my problem. I have a Hauppauge hvr 950-q that I had been using with 10.04(64-bit) since it came out with no issues at all(non that i could not fix anyways) had mythtv set up using mythubuntu and all was great. I upgraded to 10.10(64-bit) last night and cannot get sound to work during live tv. If i watch an old recording the sound works. Sound also works everywhere else on my system. Before the upgrade the audio setting in the backend configuration of the tv card was set to /dev/dsp2 this no longer works. if i put it at that(i have to enter it manually) then i have no sound and if i try to change Channel the tv feed crashes.

I have tried /dev/dsp2,1 i even tried /dev/snd/contolC1 wich i got from browsing around in /dev and found this to point to my 950-q all with same results.If i use alsa:default as the audio device in the backend i still get no sound but i am at least able to change channel.everything works in TVTime.i am simply at a loss. My next step was going to be a clean install of 10.10 but i thought i would check here before taking such a drastic step.

Ubuntu Multimedia :: Watch Tv On Monitor With Mythtv?

Jun 29, 2011

I am trying to watch tv on my monitor with mythtv. I had my card configured correctly. The first half of the Hauppauge 1600 is for analog tuning, so I have to select ivtv from the dropdown menu. I am receiving an error message stating that it cannot be opened. An hour ago It was fine. When It was working fine and everything was normal, I still could not receive any video on the tv. in mythtv. I receive a red screen. The coax cable is running from the wall into the card. I do not want to run it through my cable box for it seems difficult to configure a remote. I went to schedule direct and downloaded the correct guide for my region(which is the US). What could be the problem? I have searched forums and articles. I really want to use mythtv and cease using Windows Media Center. Does analog tv work in Mythtv. I am using the 0.24 version. My operating system is windows xp and I do not have a graphics card setup for tv-out yet.

Ubuntu Multimedia :: Converting Mythtv Nuv Files To Avi?

Sep 1, 2011

What's the accepted method for converting Mythtv's nuv files to avi files now?

I ask this because nuvexport seems to be unsupported these days. The last released version removed support for using transcode to convert the files. This leaves only mencoder and ffmpeg, and these have the following problems:

1) mencoder is much, much too slow. It takes about five times as long to convert a file as transcode ever did.

2) Ubuntu's ffmpeg is crippled, and doesn't work. I realise that there are instructions for installing a version of ffmpeg that works, but as this does not provide any method for creating Debian packages of it, I do not wish to pollute my filesystem with a mish-mash of manually installed software.

Is there any way to convert nuv files with transcode?

Ubuntu Multimedia :: Set Up With Boxee And MythTV As Media Center

Feb 12, 2010

I'm trying to set up Ubuntu with Boxee and MythTV as a media centre. I'm currently stuck at displaying a picture on my TV screen. I only have an Intel onboard graphics chip, and so I bought a VGA-to-TV box to convert the signal. This is USB powered and has VGA in, S-Video, Component and VGA out. I have it connected to an external monitor by VGA and to the TV by component cable into a SCART adapter (along with a mini-jack to phono cable from the sound card).

I was hoping that the box would handle the settings for the TV screen, but all I'm seeing are flashing lines of colour, so I'm guessing I have to change the settings. Eventually, I want to get the TV to be widescreen, but I'd like it to work first! I have created an xorg.conf file and put in three extra modes.

- first, an 800x600 VGA to PAL TV converter from [URL]... - second and third, two resolutions generated by the calculator, based on the SwitchResX settings for my MacBook to connect to the same TV. Now I'm sure you want to see a whole load of settings from my machine, but sadly I don't know what settings you'll need to see.

Ubuntu Multimedia :: MythTV Upgrade To 0.23+fixes On Mythbuntu 9.10?

Apr 27, 2010

is there any simple way how to upgrade 0.22+fixes (under Mythbuntu 9.10) to 0.23+fixes? For example any debian package (which I didn't found) to download and simply unpack and install? I'm afraid that if I modify this MythTV, Open Source DVR for 0.23 and use it on 9.10 with 0.22 I'll have problems with directories and so on...

Ubuntu Multimedia :: MythTV On 10.04 - Can't Set The Starting Channel Number

Jun 28, 2010

I have a PowerPC installation (fully patched) of Ubuntu 10, and I pulled down the MythTV suite on top (since there is no Mythbuntu/PPC that I found). I'm having an issue where after I scan for channels with my tuner using mythtv-setup, I can't set the starting channel number. Its almost as if nothing ever populates into the drop down. This seems to be specific to the combination that I have - Ubuntu 10 + PPC + Myth 0.23. If I use another x86 + Myth .21 and the same Tuner (HDHomeRun), I can set the starting channel fine. A Mac OS 10.4 + Myth .21 also allowed me to set the channel. I've rebuilt this install twice now and it won't allow me to set it. I can see the scanned data in the mythconverg database, so I know its there.

Ubuntu Multimedia :: Unable To Get Sound In Mythtv But Get In Kaffeine And Vlc

Aug 31, 2010

Have installed mythtv to kbuntu (32 bit) and configured the backend with HDHomerun and receive video but no sound The ] key brings op the volume bar but sits at 0 and will not adjust. However caffeine and he HDhomerun conf GUI viewer play the video and sound perfectly.

setting up the backend I never saw an entry for alsa or mixer, it appears somethimg is missing there for HDHomerun, although those are present when I added an entry for a Hauppauge 950Q USB tuner. Can not get this source to work as yet so have not seen the sound problem there.

The speaker test
speaker-test -c 2

also works as do the login/logout sounds and the test in system settings/multimedia.

Ubuntu Multimedia :: Mythtv Analog Hauppauge 1250?

May 4, 2011

I've looked everywhere for this and I can't find an answer. I've got a hauppauge wintv-1250 card; ubuntu and mythtv recognize it OOTB. The dvb digital tuner portion of this card works great. I had quite a time figuring out how to set it up, but it all works pretty good now. nyway, the only problem is that I need to record 2 sources: 1 is RF, the other is from an analog cable box. So, I figured I should be able to record analog video from the s-video input. Is this possible with mythtv, and if so, how? I could watch it in windows with the software that came with the card, so I know it's possible, but I'd rather avoid windows if I can.

Ubuntu Multimedia :: Very Poor Refresh Rate

Jun 5, 2011

I just built a home media server. It's using a Gigabyte E350N-USB3 motherboard with the AMD Fusion processor. So far, everything seems to be working fair enough. However, when it comes to video playback via an HDMI cable to my TV, it's unwatchable. It is okay during slow scenes, but any sudden movement or high action scenes and the problem becomes obvious.I don't know how to explain it other than it appears to have a problem refreshing quickly enough. I see horizontal lines across the film. I originally thought it might be due to low quality AVI files, but I just tried a DVD and it did it just the same.

I'm pretty knew to Ubuntu, so I'm not sure if there are some settings I can tweak, or if I am missing some drivers. Any ideas on where to start?

Ubuntu Multimedia :: MythTV Backend Can't Find Capture Card?

Feb 7, 2010

I'm trying to setup Mythbuntu on a computer connected to a TV. I have bought an USB DVB-T Receiver, named WandTV. According to LinuxTV; WandTV, aka Shenzhen Forward Video EzTV859, is supported in the Linux kernel.

When I try to setup the mythTV backend I'm being asked of what card type I have. I guess the answer to that is "DVB DTV capture card (v3.x)", but no matter what I choose, it can't find any devices.

I'm pretty sure /dev/hidraw0 is the receiver, can I use that to setup the backend?
