Yes, exactly.  I use nuvexport all the time, but I didn't know if CVD 
required different options passed to mpeg2enc and mplex/tcmplex.

Fabulous!  If I get a decent command working, I'll send it to you.  I 
also have a change in my copy that eliminates the use of mp2enc for 
SVCD audio transcoding and just uses ffmpeg to do the sound 
transcoding.  Now the question is, toolame was preferred over mp2enc, 
but now which would be the preferred encoder -- toolame or ffmpeg?

Oh, I also changed the toolame command to insert a call to sox for 
resampling.  Probably want to make the output sample rate a user-input 
parameter and put some logic in there -- no need to resample if in/out 
rates are the same.  ffmpeg can resample on its own, which is why I 
tried using it in the first place.

I've attached my version for you to compare; it could probably use to be 
cleaned up a bit.  It's just a quick hack, really, but it's been 
working for me for a while.
