I just finished setting up my new HR10-250, I choose both satellite and OTA during the guided setup and am able to watch both satellite DirecTV and OTA / ATSC local digital stations. I currently have the machine configured for one coax to satellite plus the one coax to the OTA antenna. However, I cannot record an OTA channel while I am recording a DirecTV channel at the same time. This doesn't make sense to me. I was under the impression that the HR10 has four tuners, two DirecTV tuners and two OTA/ATSC tuners. I was also under the impression that each DirecTV tuner requires its own coax to the mulitswitch and that the OTA tuners have an internal splitter so they only require one coax to the OTA antenna. So with my current setup, I should in theory be able to record one DirecTV channel and two OTA channels. But in reality I am only able to record one thing at a time. Is it possible to record a DirecTV channel and an OTA channel at the same time with the HR10? If so, what do I need to do? I can't seem to get this to work and the manual is not help.
