I am completely new to the whole "theater" scene. I am coming from the same tube tv I have had from the mid 90s. Anyway, I am having problems with DVDs in upconverting DVD players. The picture is very grainy and pixelated, and doesn't seem to be upconverting at all. In fact, it almost seems worse that the old tube tv picture. I have tried 3 different "upconverting" DVD players so far, so I assume it is not the player, but something else. I am completely new to all of this and need some help. The TV is a 37" LG LCD, 1080P, 60Hz. (model 37CS560) The HDMI cables I am using are these Daytons; http://www.parts-express.com/pe/showdetl.cfm?partnumber=181-772 The receiver is a Denon AVR 1610. Is the problem the receiver or cables? Maybe the TV? Do I need to adjust some sort of settings? Again, I am completely new to all of this. Thanks in advance.
