Sometime in the near future I hope to have a 3D TV, so I'm looking at a new receiver. We currently have two HR20 and use the OTA capability infrequently due to rain fade, but frequently enough that I'd like to keep that ability. Does the HR34 support OTA? UPDATE: I see in another thread I need an AM21 to record OTA. I wonder if they'll throw that into the deal when I make it? I also have an external 1 TB HD on one of our receivers and I presume that a new receiver wouldn't accept it. If anyone knows of a way to get my stored programs copied over to the new receiver, please let me know. I should point out that I have an iMac. Other than the initial charges for the unit, are there any one-time or monthly fees that go with this receiver? I doubt we'll use the whole-house option but I would like to hook it up to my wifi. Is the HR34 the only one with more than 2 tuners? Those additional tuners, do they have any limitations? Like maybe only one tuner does 3D? There have been times when I wanted more than 2 tuners. Does the HR34 support ESATA? Are there special requirements to install this receiver? Different dish or cabling?
