Might I have some electrical interference with the cable that runs from the media box to the panel? That's about all I can think of. Or are all of the 4360/5360 like this and the noise is just so insignificant that nobody complains?
I have it a lot, too, on my new 1140. It bugs the living heck out of me sometimes. The Hi-Def and the upconverted SD on the 1080i/720p channels doesn't usually have it. It's especially evident on the 480i channels, and it doesn't matter if it's low or higher quality material being shown. My SD E* satellite signals, which are not so great to begin with, are just plain horrible-looking a lot of the time. But even my digital 480i OTA channels aren't very good. Some of my analog ones even look noticably better - they don't show any noise and are really clean. I usually have to crank up the mpeg noise control, sometimes to "high", and turn the sharpness down a lot. I also found that if you take it out of "Standard" screen mode and put it on "Game", (or even "Movie" as a 2nd choice), it cuts it down quite a bit. "Standard" is too bright and exposes it more.
I've never seen or had a plasma with such a bad problem with noise. I sometimes wonder if maybe something's wrong with it. I'm constantly debating whether I should bring it back when I'm watching SD, which is at least 85% of the time. It can be pretty tough to sit through.
The only thing I do know is that, in a few reviews I've read on Pio's, they mention that they tend to be very revealing of flaws and artifacts in low-quality sources. But even still, it does seem to be pretty excessive.
I had the Panny 50PX600U before this, and it didn't have anywhere near this extreme of a noise problem with 480i SD.
I've got my set plugged into a halfway decent line conditioner/supressor, so I don't think it's due to electrical interference. It doesn't show up at all with any of my other gear. My stereo has no background noise whatsoever, and is clean and as quiet as a mouse.
