Ubuntu Multimedia :: How To Watch Streaming TV In Standalone Player

Guetting radio streams to work in ubuntu stand alone players wasnt so difficult after all: I just had too see the page source and locate the streaming address. That way I added some radios I was interested to rhythmbox. I also found websites that list lots of streaming addresses for Europe, Japan.TV seems to be different: so far I havent been able to do the same: Ideally, I could search for a streaming tv address in the source of the page with the embedded player, but no luck at all.

Im not talking about tv via a tvturner card, just tv streamings, like the BBC or this german one URL... type=null. The public german broadcaster allows me to watch their programms in their embedded player. Can I watch those programms in vlc or in other standalone players? Im also interested in the same for the bbc, cnn, aljazeera...
