I've had the same thing happen to me when using the mencvcd script. I'm
trying now to include the -cdsize option, and hopefully that will make a
difference. I didn't manage to get very far on encoding an mp4 file with
it - the file in question is 900+megs, far too big to fit on a CD, and
'file' reports it's Apple Quicktime. I'm now trying to use gmencoder on
it.

mplex is what you want to use. The output of mplex is appropriately
sized chunks of the original file. mplex multiplexes the video (mpv) and
audio (mpa) components. If you are lucky, you'll get a file that won't
be out of sync (audio with respect to video). Currently, that seems to
be the main difficulty I'm facing. That, and not having enough
intervening disk space to hold all the intermediary copies (avi, mpa,
mpv, cd image, etc.)

Anyway, if you try:

mplex -o movie%d -S 700 movie.mpa movie.mpv

you should then get a number of files (movie01 movie02 etc.) which then
can be turned into VCD by using vcdimager.

It's not just you - I once ripped an episode of Outer Limits (new) from
DVD. A single episode, about 45-50 minutes of video, and the resulting
avi file was 1.6 gigs. O my poor hard drive :). gmencoder seems to try
and tailor the output to appropriate CD-sized chunks, but that's not all
that useful IMHO when the desired output is SVCD or VCD.
