Not sure if this might be better posted in the AV Equipment forum, but we'll try it here first.... I'm curious about the difference between american and British DVDs, not so much in terms of the region 1 / region 2 encoding, but in terms of the differences between PAL and NTSC. The PAL television system uses 625 lines (about 580 useful lines) and displays 25 frames per second (using interlacing, so 50 half-frames per second). NTSC uses 525 lines (about 480 useful) and 30 frames per second (again, with interlacing). So, questions: 1) If we ignore progressive scan for a moment, does the output from a PAL DVD actually have a higher vertical resolution than the output from an NTSC disc on the same player? 2) How do they go about putting a cinema film (24 frames per second) onto an NTSC disc? And is the process the same for PAL? I know that when they show films on UK television they actually speed them up slightly and show them frame for frame. But showing films on NTSC television is more complex. I believe they have to blend together successive frames. (You get a similar effect watching american shows on British TV). Does this imply that the individual frames on a PAL disc are sharper than those on an NTSC disc (for example if you freeze-frame it, will you always see a sharp rather than blended picture?) 3) To be able to play back an NTSC disc on a multi-region enabled player, to what extent is it helpful or necessary to have an NTSC-compatible television? 4) Does anyone have any idea when a PAL progressive scan standard will be finalised? And how many current progressive scan DVD players will be able to support it, if any?
