Even at 640x480 it's probably more than double it's native TV resolution. According to a bit of googling I did NTSC has a standard scan line number of 525 and a ratio of 4:3 so has an effective resolution of 700x525 (or 525 by 300 if my maths is screwed) which means it needs to be fiddled about with quite a lot to fit it into 640x480 (actually reduced or increased - I don't remember which). Early TV cards used compression to get the mass of pixels to the screen at a reasonable speed too meaning the picture may contain compression artifacts as I doubt it is loss-less compression. -- -- Mark Benson Any spelling errors are attributed to PEBKAC SilValleyPirate - AIM silicon_valley_pirate_uk - Yahoo!
