CBS HD Football blocky?

I'm just trying to figure out if it's my tv, or what...but when I watch football on cbs hd it's extremely blocky. it's clear as day on nbc and fox.

I have a 720p 42 in samsung plasma and I have ATT uverse.I initially thought it was because of uverse, but it's just as blocky when I try to watch over the air. Is anyone else experiencing this?

Welcome to High Def Forum. This area is for cable. There is an ATT Uverse area of the web site. There is also an area for high definition programming and shows. That area could help you find out if others are having trouble with CBS. Try posting in one only of these areas of the web site. You will get a reply much more quickly.

PS I have not had trouble with CBS, they are very reliable.
