Hi all, I have 2 questions about this set, I am about to buy one but need clarification first 1. Does this set "downconvert" 720p to 480p? or does it "upconvert" it to 1080i? or 960i? 2. wht is the deal with this 960i anyways?? this tv is capable of 1080i right? or is everyhting displayed at 960i? Thank you!
