I got fed up with the 811 freezing when using it for OTA HD. Got a Mits with built in tuner. Much better picture (richer, great color, excellent contrast without having to boost cointrast control which I had to do with the 811) and no lock ups. However, the 811 performs very well on all five of the satellite HD stations(I guess we call the movie channel HD). It's impossible to be objective, but my wife and I both believe that ESPN and Discover HD usually produce the best pictures and they're from the 811 (but I assume a different chip set than used for OTA).
