4:3 or 16:9, if you play with mplayer from commandline do you see
something like:
Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.
VO: [xv] 704x576 => 1024x576 Planar YV12
if yes, you don't have to scale, and the aspect can/will be read from
the sourcefile, it is already in the right format.
- my TV screen in a widescreen.
