Hello my friend's home theatre is in the process of being made... He built it before we tumbled upon this forum and AVSforum so yeah we may regret a few things but oh well. Bear with me, I forgot model numbers and the manuals have multiple model numbers written on the cover. Mitsubishi 55" rear projection ($4000) Sony DVD player ($120) (non-progressive scan) Yamaha 5.1 receiver Klipsch center channel and 2 front towers. (no sub or surrounds at the moment) Monster cables The problem is when we are watching a DVD movie.. the TV has the option for 960i or 480p (which also confuses me cause the TV says 1080i on it). If we choose either and then push the info button it still says 480i. I've tried messing with the DVD player which is very simplified and the TV display controls. It said in the TV manual that when switched to 480p, the TV is supposed to serve as a line doubler and help produce a better image with less flicker. But we can't get it to change to 480p. Is it because we don't have a progressive scan DVD player or the TV has a bad line doubler? I noticed the picture isn't as good as a lot of other TVs I've seen playing DVDs. The screen appears to be moving around and sometimes there are purple outlines when an Image is displayed on white backgrounds. The TV's primary use is ONLY dvds and laser discs because we watch cable TV in a different room and don't have an HDTV tuner. My friend's parents went to pauls tv's and best buy for the equiptment. They don't know how anything works right now so I'm trying to help them out. thanks.
