I downloaded the file, and ffmpeg tells me it's h264 video and libfaad
audio. Perhaps youtube converted it when you uploaded?
Anyway, it plays fine on my Lenny amd64 system using mplayer from
www.debian-multimedia.org. But it does not play at all in VLC or Totem.
One thing I do notice is that all the music is coming from the right
speaker. The left speaker just has some low-volume noise.
Use avidemux to make a short clip of the video (about 5 MB), and email
it to me. I'll do some testing on the file with its original encoding
over the weekend.
