Cool.

I burn to SVCD - which is MPEG2, but a lower resolution / bitrate
than DVD... some of my instructions might help you on your quest...

See my webpage -

TMPGenc works pretty good for editing an MPEG2 stream, as long as you
do it frame by frame. I transcode into a bitrate low enough for SVCD,
so YMMV - the Cut & Merge function of TMPGenc is rather buggy,
however.

If you're looking into coding into DivX, NanDub is prolly your best
option.

HTH,
