How do the american HDTV´s work, they have a double amount of lines don´t they. Do the sources then have an HDTV signal (is that an progressive scan signal) or do the TV´s have a line doubler or something. And is there a reason not to buy a hdtv TV from the us and use it here, and have an progressive scan dvd player and therefore get hdtv images, would that only work with ntsc dvd´s or could a dvd player modify a pal signal to ntsc? How the hell does all this stuff work? Is it a must to get an european TV like the pixelplus, arent most TV´s now compatible with both pal and ntsc signals, and like me I think about 95% of my DVD´s are region 1 so does it even matter.
