Cropping to 720x576 hardly will help when the video is already that
size.
It looks like whatever produces the image didn't like that 720x576
is an odd number of macroblocks (45*16 x 35*16) and simply cut it down,
adding a that white and black border on purpose.
So you'll have to crop to 704x560 if you want to get rid of it.
