Since your plasma can display at both 720p and 1080i you should be able to set your PS3 to output at either of those resolutions settings. And if you have your PS3 hooked up to your TV via HDMI it should upconvert your DVDs to whatever resolution setting you choose too. Upconversion will not take place via component though.
hope this is the correct forum. i have a panasonic plasma (TH-42PX60U) that displays at 480p/720p/1080i and i'm using my ps3 as my primary dvd player. i know that the ps3 doesn't upscale normal dvd's. but when i play video games the reolution is at 780p. i'm by no means an expert on plasma's, but when or how can games and dvd's scale to 1080i? thanks.
