my experience thus far has been that, even with the best digital sources (I prefer satalite over what cable is doing -probably less compression, as well), especially HD DVD/Blue Ray, that most plasmas and LCD's suffer from lots of digital artifacts, depending on how good the processing and scalers and such are, that are being utilized! - among other issues. Basically, I think things have a way to go to improve in this new ALL DIGITAL world of tv's.
What I notice most when going through the line-up of flat pannels at the local chain AV stores, is lots of digital pixelization, motion artifacts, and moire problems in large video fields, even from HD sources! This is rather anoying to me, personally. I much prefered HD on analog equip over the years, consistently.
That all said, I think (hands down) the Pioneer Plasma's wipe the floor with the competition for pic quality from most any source out there currently! When I watch HD sources, especially sports on these sets, I find much more stable images, less "blocking", motion problems, and get an overall fealing of a more accurate image from Pioneer's than any other sets I've seen!
Has anyone else experienced this with the Pioneers?
