Well, frankly, 15 seemed good enough on the Dangerous discs I was working on... > Thanks for the reminder, Jay :) I forgot TVs do that 2 fields trick. :-) It's not widely remembered that NTSC is a 720x242x60 system. > > I don't know that I'll have Xinerama support on the Tritton USB VGA > > dongles I'll need to use; I plan to have 3 or 4 channels of video going > > simultaneously.

True. But we're not *playing* video.
