Hey guys, I've found some pretty good info on here, so here's my first post. I'm wondering what exactly are the Pioneer plasma's doing when they accept a 1080p signal, as per Pio's website (Ability to Accept a 1080p/24Hz Signal). Is it "downconverting" the signal? I'm a little confused... I ask because I'm going to be getting a Pio 4270 in the near future and will be hooking it up to a 360 which of course has the options to choose 720p, 1080i or 1080p. I have a friend with the Pio 5070 and he runs his 360 at 1080p and it looks incredible. What would be the best signal to use?
