Yeah, I have to admit, I am getting really sick of this as well ( I too have an H20-600). The HD aspect is pretty much useless to me, as far as the receiver constantly resetting itself while watching any type of HD programming. I am thinking of having D* replace it. However, there is one thing holding me back from doing it. I've read in the forums that the OTA tuner on the 600 is better than the 100.
My question to those who have owned both the 600 and the 100, is there really that big of a difference with the OTA tuners between the 600 & 100? Any response would be appreciated.
