I have two questions: 1. In setting resolutions, I discovered that my 6 year old Mitsu projection TV does not accept 720P feeds(it says so in the users manual), so that I have to have my HR 20 set with the native off. If it is on and I tune to channel 73, I get a blue screen since the TV doesn't know what to do with the 720P that ESPNHD uses. So I keep it on 1080i with native off, but my question is what does my Mitsu TV actually receive since ESPNHD does not broadcast in 1080i ?????? Is the HR20 upconverting ESPNHD to 1080i which my Mitsu TV can handle? Question 2: Is there a way to program the remote so that I do not have to toggle to AV1 from the DirecTV position in order to adjust the volume on my Harmon/Kardon receiver which is powering my surround sound?? It sure would be nice if I could leave the toggle on DirecTV to change channels and adjust the volume!!!
