Hi folks, First time poster here. I bought a new 42" Panasonic Plasma a month ago. I'm new to HDTV. It's the most recent 720p/1080i one in Canada that's not native 1080p. SKU TH42PX75. I've noticed a few things when watching/playing HD games or HD TV stations. Xbox 360 - looks fantastic, a big step up from my old 27" CRT. No issues. HD TV show/movie channels - hit and miss. Some HD feeds look fantastic (no graphical issues), while some look mediocre. For medicore feeds, I can tell it's some kind of HD feed, since the resolution is higher, but I notice some TV shows/movies have weird shifting pixels. It's as if a thin layer of colour is moving around even when the screen is still. It's most apparent when looking at someone's face and cheekbone. Is this problem my TV, maybe bad cables or HD box, or just the HD TV channel's weird feeds? HD sports channels - these HD feeds usually look much better than a HD tv show or movie. I've been watching HD US Open Tennis and it look's phenomenal. I get shifting pixels in some sports (mostly the grass in baseball games), but by far not as much as tv/movies. Some HD feeds look perfect with no issues. Thanks.
