I've spent 4 days with my new 50" 1080p Samsung 5084 plasma, and I can tell you some of the new HD broadcasts on HDNET or MoJo are very impressive and show very few flaws on this panel. However, some of the older movies broadcast in HD definately look noisy. I'm shopping for a good upconverting DVD player currently, but I'm concerned that upconverting the older DVDs is not going to look all that great - if the content is not there, then upconversion is not going to make a 480 look like a 1080, not matter how good the conversion is.
