Can you elaborate on this?  Do you mean to select "audio processing"
but deselect "video processing" ?  Or do you export the audio, and
then make an avi out of the original video and the new audio file?  I
have tried several scenarios, all unsuccessfully, but I'm not 100%
sure if I've tried what you're suggesting or not.

Yes.  Me.

There is, at least, an issue with nuv's and avidemux2 that is
independent of the driver.  It may, however, depend on the contents of
the nuv file itself (i.e., rtjpeg/mpeg4/hardware mpeg2 from a
pvr[23]50).  It would probably be a good idea to include what kind of
nuv you're dealing with in all success/failure reports.

Chris, I take it you're using software compression?  RTJPEG or MPEG-4?
