Hi. I just put together a new home theater and I am concerned about an issue. I have a Panasonic rear projection DLP HDTV. The PT-52DL52. And I and I use a Denon 3800 for dvd's. The picture clarity is amazing and it is very sharp. But I have a concern about some flickering. When I watch DVD's There is a noticeable flicker in the picture. It doesn't always flicker, just at certain times. When it does flicker, it is more in the background,but not all of it, and sometimes it can get REAL bad.I watching "Ice Age" yesterday and the picture was very smooth with no flicker, then it came to a certain part and it began flickering. It flickered for a little while and then stoped and was smooth again. I rewinded it and played it again and this time, the part that was flickering was not flickering at all and was completely smooth. This leads me to believe there is something wrong since the same part can flicker at one time and then not happen again. I would expect a more expensive HT like this would not do that. I had Panasonic come out to look at the TV. The guy watched the picture for a little while and said there is nothing wrong with the TV. He said that is due to compression on dvd's. I would think that the dvd player would be able to correct that. Due you think that there Might be something wrong with the player? Is there anything I could do to fix this problem, or at least make it a little better? Do you notice this with your displays? Do you have any suggestion? Also, have you ever reviewed either of these products? Also, when I turn the DVD player on, there is a faint circle that is on the middle of the screen about 3" in diameter. You can only see it when ther is no image on the screen. Is that normal? Thank you for the help.
