In fact your explanation of broadcast tradeoffs is better than the one I used to flame Bill (who did say it). BTW, you can get square pixels with NTSC, you just have to get the vertical and horizontal size right or mess with the dot clock. The dot clock is probably the best way but there are often constraints on it that come from the system itself, like coordination of the video shifter and the memory cycles. (Using VRAMs neatly avoids this.) Todd Whitesel toddpw @ tybalt.caltech.edu
