As to ffmpeg2theora, I'm using version 0.24 from http://v2v.cc/~j/ffmpeg2theora/
When using FFmpeg proper, I'm using their recent version 0.5 and have
found that it does decode the 5.1 audio correctly. IIRC, older
versions needed liba52, to do this correctly (although I may be wrong,
since it's been a while.) However, FFmpeg 0.5 no longer needs this
(indeed... the configure command barfs when you try because
enable-liba52 is no longer a valid option during compile.)
According to the changelog ffmpeg2theora, was bumped to ffmpeg 0.5 on 3-12.
It appears that the FFmpeg versions are the same in each case, so it
seems to me that the output should be the same as well.
