OIC, but since I *do* intend to do playback on TV, what side effects are
there, if any ?

That'd be a great step ahead :)

Hopefully this will be a configurable option ? Since I crop my
"cinemascoped" movies an aspect ratio would be no good idea ;)

You do have a way to analyse the pictures using something like

mencoder -cropdetect -i mymovie.mpg -frames 500 -o yugga.avi

but this is far away from being perfect since f.e. a TV stations logo
which appears in the black area lets "cropdetect" think, the movie
starts at that vertical position... But cropping by hand is *very*
effective resulting in a much smaller sized AVI :)

I didn't try that codec yet. I *very* much like "lavc" because it gives
me up to 65 fps on encoding and offers quite remarkable results in
quality :)
