My R-10 just bit the dust, all it says is Welcome, and never boots. Tried reseting, unplugging etc. DTV said they'll send me a new one at no charge (well that's good) But I was thinking, maybe I should go HD and buy the 15. So I called DTV back and and inquired about it. The thing that I'm trying to figure out, what is exactly different about it, compared to the R10 other than HD. I don't understand this OTA deal. So if you swicth to HD you don't get locals anymore? You have to use an outside antenna? Gee, that sucks. Can someone point me to a comparason area? Will I still have the same Tivo options, recording options and such?
