Thanx, but i allready know those things and i'm trying to write a 'simple'
shellscript that will
apply all these 'rules' and spit out all the options mencoder needs to do
that given task.
Hell, i've even thought of playing with perl to display an image taken with
mplayer -vo jpeg
(or whatever...) for the crop selection :p

Anyway, what i really wanted was someone to try 'mplayer -dvd 1 -vo
null -nosound' and
tell me if it's working or not ;-p
