You have one or more decoders which convert the incoming composite stream into RGB and sync pulses. Beyond that point they're as system-dependent as the monitor in front of you. The decoders themselves are so cheap that you'd think it would be easier to build multisystem VCRs. > I'm quite certain that if I hooked up a splitter from the VCR > or the DVD player and put the same video signal on both TVs, it > would look better on the true native NTSC format television than > they would on the one that has its own built-in NTSC/PAL converter. Well, you could try, but even then it would be a comparison between individual devices.
