I just got a second HDDVR. I now have two in the same room about three feet apart. The old one -remote RC34 is an HR20-700 The new one -remote RC65R is an HR21-700 I have spent 37min on the phone with D* now, three separate tech's, none of them have had to do this before... really? I have tried all options. The RC34 remote is set to IR (the original setting) The RC65 remote is set to RF now The RF setting is very hit or miss, sometimes 5 to 6 button pressings to get it to move or respond at all. Can someone please tell me what to do or direct me to a thread that covers this issue please. They had me try every AV1/AV2 procedure but it always locked-up the RC65 remote and accomplished nothing. Please help.
