Okay I just purchased a Insignia 20" HDTV and its output signals are 480i, 480p, 720p, 1080i. I'm thinking about purchasing a HD-DVD player for the 360. Will I be able to watch HD-DVD movies on the HDTV I have?
And is there a major difference between 720p and 1080p?
I heard that if your HDTV is small like mine, I have a 20" its not noticeable. Is that true?
Edit: I do have 2 HDMI ports in the back of my HDTV.
