I'm interested in the latter solution (storing the aspect ratio in the avi)
I wasn't aware that mencoder does this automatically. So, all I have to do
is scanning the input stream a few minutes with mplayer -vf cropdetect,
grepping the crop setting and running mencoder -vf crop=...  Am I right ?
this will be ok even with 544x576 anamorphic (which can be 4:3, 16:9 or
2:35) ?

Thanks.
