We have it. We have direct tv. I personally only watch NFL football in HD. My husband will watch pretty much anything so he watches alot in HD when he is home. It is worth it to him, not really to me. We also have the seven in one surround sound, and I will be getting him an HD DVD player for Fathers day just because he is hard to buy for. I hear they are coming out with more HD tv on Direct tv but not sure when.
I think the only thing we have an issue with is CBS Sports. We haven't had much luck with their HD.
