After a couple of days rest, I have fixed up that code a bit, and will
send out a revised version this weekend; I can post it to help-vcdimager,
too. The code allows you to give vcdimager a file which specifies how
to create PSD.VCD --- you define a series of selection lists and play
lists and tell how to link them together. (It also affects/effects
INFO.VCD as well, since that is just the list directory.)
It only allows you to do this with the VCD2 format, just because that
is what I was testing, and I didn't go and try to figure out if it was
sufficient for SVCD as well.
I am in the midst of adding code for specifying tracks and entry points
to this scheme, which would allow you to accomplish this:

To this end, I've got a question about "entries": exactly when/how are
they used? Are they used at all when the disk is played without PBC,
or are they only used when a PSD List Item specifies 'entry #N' ?
The entry lists created by vcdimager, and the one on the lone commercial
VCD I own ("Duran Duran's Greatest") are both the same: one entry for
each track, containing the track number and the absolute MSF start point
of the track. If you create extra entries, which point into the middle
of a track (absolutely), what is the purpose of the track number?
(I guess I can figure some of this out by playing with it, but why waste
time if someone already knows the answer....)
After that, the only thing left will be "segment items"....
