I've not done SVCD, but here's a script that I use for converting PAL DivX
to NTSC VCD. Change flags as needed to get SVCD instead and you should be
off and running. Uses mplayer. This will convert a DivX to VCD slightly
faster than realtime on an Athlon 1800+. This is NOT a "real" PAL to NTSC
conversion, just a resize and frame rate adjust, but it has worked on
every PAL DivX I have tried it on.
NOTE: The "42336" in the sox line is a calculated rate based on 24/25 of
the rate in the PAL DivX -- in this case, 44,100. If your DivX audio rate
is 48,000, use 46080. I have occasionally had to tweak the audio rate a
bit to get the sync to come out right, but it generally works frst try.
