TNT-HD looks pretty bad, IMO. It doesn't look like real HD with the exception of few sport programs. My guess is that it's just widescreen SD and there is a lot of motion artifacts. I used to have Dish before and TNT-HD was exactly the same. Terrible programming, about 70% of Law and Order (repeat) and picture that looks like expanded SD. I want TMC-HD, STARZ-HD, CMAX-HD. TNT-HD is just another "cheap" channel.
