I just upgraded my satellite receiver to HD with a H20 Directv receiver (with no serial connection). I have searched high and low for the IR code so I can change the channels of my H20 Directv receiver through my Tivo (and record, etc.). 1) Yes, I have the receiver set to IR, and not RF 2) Yes, I searched the nice fellow's forum posting with every IR code made so far, and no, the H20 is not listed, perhaps because it is new. 2a) Yes, I tried the codes of the H10 and other Hughes/Directv receivers and they don't work. 3) Yes, I called the Tivo support line and they are stumped. They say they have no documentation on the H20 because it is new. 4) No, the Tivo tech support folks do not talk to the engineering folks and are not able to tell me when they might have such an IR code. 5) Yes, I am hoping someone stumbled upon it already!!! Thanks for any help!
