So, essentially you're saying that MPEG2 without B-frames is perfectly
legal from the DVD standards p.o.v., right?
I'm asking this because standalone players are quite anal w.r.t. the
lt to tell which way the market will go.
However, the vast majority of the newer DVD players will happily play
both formats, even when they only advertise one of them. Strange, isn't?
On the side of the old-ish players, DVD-R has slightly bigger chances to
play without problems.

How can i tell mplex to not split the file, because i want to put
everything into one SVCD.
If that's useful, here's the mpeg2enc command line i used to generate
the video stream:
mpeg2enc -v 0 -f 4 -F 4 -n n -o "cass1".m2v -a 2 -I 1
containing the DivX5 codec, with the
libdivx files installed in /usr/lib, not in /usr/local/lib. This way i
got zero problems with software depending on DivX.
Not to mention that installing/uninstalling RPMs (or any kind of
