Sure, can be done... I'll leave this to crimsun as he knows more about
vlc than I do
Judging from your and Matthew's comments I think we should leave
everything as it is, move already in multiverse parts of ffmpeg back to
universe and wait for ffmpeg to release something stable.
And in the future when there's something with vlc or ffmpeg I'll talk to
you directly first ;)
Only one last question... quote by Matthew...

Do you have a list of all parts of ffmpeg and whether they're really
free or patent covered?
PS: sorry for all the hassle
