At what stage did it 'mess up' the sound?

Do you mean the *rendered* video had messed-up sound?
If so, what were your render formats and settings?
Cinelerra renders perfectly with some standards/settings and fscks
things up a tad with others.

I get the most reliable rendering by either:
1) Rendering video-only through yuv4mpegpipe and audio to wav, then
interleaving them with ffmpeg, as described on the page
http://crazedmuleproductions.blogspot.com/2007/06/beginners-guide-to-exporting-video-from.html#dvd

OR

2) Rendering out to DV, then using ffmpeg, mencoder, transcode or
whatever to downgrade to the desired target format(s).

Keep trying with cinelerra, and join the community on irc.freenode.net
#cinelerra and #openvideo. For me, a modest amount of learning time has
paid off handsomely - cinelerra is way from perfect, but for most
situations it's the best all-round linux-based video editor. You do get
used to it pretty quickly.

My strongest criticism of Cinelerra (which applies equally to kdenlive,
openmovieeditor etc) is that it doesn't provide any mechanisms for
losslessly grouping tracks. For even a basic 20-minute doco with dozens
of source clips, transitions, chromakeys, insets, voice-overs and
background music, editing with these basic editors is a labourious
hair-greying PITA.

Cheers
