I found nothing specific about this (and I don't want to pay big $$$
for the official specs), so I'll just stick to these in the next
version. For DVD, I found out that it's even 15 for PAL and 18 for NTSC.
So I compared two videos, one with 132, the other with 15, I don't see
I just uploaded a new version of the script with the new values
(defaults are the PAL values).

Sounds good. I actually made SVCDs with keyint=132 which work on my
parents' DVD Player (cheapo Dayton DVD777). But didn't try seeking.
