I am deliberating 24/7 on whether to buy the current 65h80 or wait for the new models. The new ISDC Pro doubler seems to be the biggest "advantage" in the new sets. I am not an expert by any means so can anyone enlighten me on 540p vs. 480p. I am primarily concerned with it's impact on DVD's. I understand it is 60 more lines of progressive but I thought DVD's native format was 480p so won't those extra lines just be overscan or introduce extra artifacts that were not there to begin with?
