Software :: Unable To Convert MKV File To AVI Using Mencoder

I have a MKV file and need to convert it down to XVID to allow some of my other streamers to use the file. However, when I try I get the following errors:

Too many audio packets in the buffer: (4103 in 8255236 bytes)

and

Maybe you are playing a non-interleaved stream/file or the codec failed?2:128] For AVI files, try to force non-interleaved mode with the -ni option.

The file details are :

General
Complete name : Test 1080p.mkv
Format : Matroska
File size : 10.9 GiB

[code]....

and the command I am using to run the conversion is:

Quote:

mencoder "Test 1080p.mkv" -channels 6 -ovc xvid -oac mp3lame -xvidencopts pass=1 -o /dev/null -lameopts cbr:br=128

I presume that it has something to do with the 6 channel DTS audio and the conversion to mp3 because if I change the command to just copy the audio all progresses fine.
