Murray,
Another thing to try is to NOT render directly from Cinelerra to your
final output format. Instead try an intermediate format for both audio
and video, then use ffmpeg or mencoder to encode those intermediate
files into your final video.
For example, export your video as a YUV4MPEG stream with the following
command,
ffmpeg -f yuv4mpeg -i - -y -threads 2 -vcodec huffyuv -f matroska %
and change the file extension to .mkv (extensions don't really matter,
just a convenience). Beware, exporting as HUFFYUV creates LARGE files
and you must specify framerate later to mencoder (with -ofps 30000/1001
for 29.97 frames per second), but it works like a charm and then you can
choose different qualities for encoding the final video (ie one
resolution/codec for youtube and another for DVD from same source).
Export audio as a microsoft .wav and then convert to AAC, MP3, OGG,
whatever.
Mux the video and audio together into your final formats. Plenty of
examples available online, just search for "mencoder mux video audio" or
the like.
I'd caveat the above works using recent SVN version of cinelerra, ffmpeg
and mencoder. Its not too hard to install the latest SVN versions and
the often increased compatibility and stability really pays off in the end.

Would you care to give some live examples about obove for us newbies -
thanks :-)
