The aspect ratio information really changes as you can see:
(consider only the first nibble of a/f, the second one is unrelated)

$ mpeg2desc -u <gigolo_small.dump |grep "sequence hdr"

what should we do, ignore the change? or maybe do you
prefer to use the A/R reported by the ifo if available?
(using a new STREAM_CTRL)
This last solution would have the positive side-effect to
restore proper playback of recent dvds that are more and
more often played as 2.37 by vd_ffmpeg
