If this means that reading /dev/video would no longer deliver AV_PES
packets, this would immediately break 'vdr' :-(

Scanning the AV_PES packets to see which is video and which is audio,
and how long they are, is probably a lot easier than scanning actual
MPEG2. So I'd vote for having at least the option of getting the packets
the way we get them now.
