Samsung manufactued the TV both ways, and claimed the picture looked better with the reflective screen. A few of their models have flat (meaning non-glare) screens, but those are harder to find, and may only be 720P.
Someone earlier posted about compressed video signals. Amen to that. Cable feeds and even satellite are heavily compressed and it drives me crazy. The irony is the absolute best way to watch HD content is by free over the air digital signals. These aren’t compressed at all, and sports programs look FANTASTIC. It’s funny, I can’t stand basketball, but it looks so incredible in high def that I will actually watch it from time to time. You can count the floor boards in the court. The other best way, as was stated before is with high def disc formats like Blu Ray and HDDVD. I am hanging on to HDDVD with a passion, sort of like the old laser disc guys. HDDVDs can still be found for incredible bargains, and as long as the players I have to watch them on still work I intend to enjoy them.
