I just used a rather simple script. This is it:

#!/bin/bash -x

mpeg2dec -o YUV $1.m2v | ~jbj1/fix_tivo_video $1.edt | yuvdenoise | 
mpeg2enc -f
4 -q 7 -o $1.svcd.m2v
mpg123 -w $1.0.wav $1.m2a
~jbj1/edit_tivo_audio $1.edt <$1.0.wav >$1.cut.wav
sox $1.cut.wav -r 44100 $1.1.wav
toolame -b 224 $1.1.wav $1.1.m2a
mplex -O 150 -f 4 $1.1.m2a $1.svcd.m2v -o $1.mpg
vcdimager -t svcd $1.mpg -c $1.cue -b $1.bin
rm $1.svcd.m2v $1.0.wav $1.cut.wav $1.1.wav $1.1.m2a $1.mpg

My "edit_tivo_audio" and "fix_tivo_video" are programs I wrote to 'edit' 
out video and audio frames after I had scanned through programs to 
remove commercials. Basically they just drop frames according to a text 
file generated from my "editing" program. Since I was re-encoding 
everything anyway this was easily done.

Ouch, yeah. Do some searching on the mjpegtools mailing lists. I seem to 
recall someone has written software that can change ntsc to pal and vice 
versa.
