Ah, that makes sense. Which leads me to: sometimes, the picture distorts

sends PAL@720x576, actually. Sometimes, there are also color strips.

FWIW taking only every third line of it and applying this math on the
offset:
offset_in_bitmap = x + 2*576*y/480;
makes some parts of the picture what they should be. I have no idea if
it helps anything though ;). IOW, the skew at the bottom of the picture
seems to be 576*2=1172 pixels for whatever reasons.
