The raw video is fine for converting to other formats like mpeg 
(although I don't if or how to interface them with transcode -- any one 
else know?), but the majority of people who contact me about nuvexport 
just want to save the files into a format that can easily be played back 
with xine/mplayer or on a windows machine without the dsmyth filters.

All I know is that there are horribly AV sync issues when using mplayer 
or avidemux2 to convert from nuv to avi using a stream copy.

It's in nuvexport, and is a rather crude hack using a gtk->curses 
wrapper and avidemux2.

Well, I'll keep hoping that it might happen, but will look for a way to 
make transcode deal with the raw stream.  That should satisfy at least 
the people who want a standard dvd/svcd exporter, and divx/avi exports 
will just have to reencode for now.
