I'm very close to buying (or should I say leasing) a new HR10-250 from CC. I get very good OTA reception with my Sony TV and Terk set top antenna, but after reading that a lot of people have bad OTA reception on the Tivo even when they have good reception when their antenna is hooked up directly to their TV, I'm worried. I don't want to degrade my OTA signal - after all the whole reason I'm get the Tivo is to record my OTA HD. Is there a way I can test or use the OTA tuners on the unit before I call into D* to activate it? If I get really bad OTA reception with it, then I won't want it, but the way I understand it, once I activate it with D*, I'm stuck with it.
