didn't test recent versions yet, still at mjpegtools-1.6.0.

'transfron' uses this command line for svcd conversions:
transcode -i source/ -y mpeg2enc="-a asr -b bitrate -n p -S junksize -B 224"
 ,mp2enc -Q 5,5 -V -Z 480x576 -F 4 -E 44100 -b 224 -o destFileP -q 0

i tried 'tosvcd' once. nice tool, but it doesn't allow that much control
over the conversion process as using 'transcode' and 'vcdimager' step by step.

i'm not that familiar with dvd-video specifications ( valid resolution, interleaving ). is dvb-mpeg2 video and audio a true subset of dvd-video video and audio?

'requant' promises a fast way to reduce video bitrate, but as fta channels are already quite stingy with bitrate ( 3-4 mbitps ), imho there's no room for further quality reduction.

i really don't understand why vcd/svcd is used that much, dvd+r media is
already cheaper per mb than cdr, and dvd-video a much cleaner ( less streched )
standard.
even mpeg4 capability is getting more and more standard in standalone dvd
players, so why care about vcd, svcd, mvcd, xvcd, ...?
