I've just been reading through this thread.
So If I do the crop to 702 pixels, and converto to square pixels, that should be correct?
I just found this. Wow.
Quote:In an ITU rec.601 PAL video capture (virtually all PAL capture devices follow this standard) the 4:3 image is in a ~702x576 portion of the 720x576 frame. So if you want very accurate upscaling you should crop to 702x576 then upscale to 1440x1080. As was pointed out, if you upscale the full 720x576 frame to 1440x1080 the aspect ratio will be about 2 percent off.
