For future reference - I think RF mode only works on the DirecTV swoosh remote option, not AV1/AV2.
i'm sorry but you're wrong, I have 3 different receivers controlled by RF, using one RF remote.
For device to accept RF remote programming it has to be programmed with one of the following IR codes from 00001-00008. In the case of older RF remotes, 00001-00004.
When you're switching receiver and remote from IR mode to RF mode, its best the device is programmed with address the receiver was programmed for. But in the case where you're programming a second RF remote to given receiver already in RF mode, it doesn't matter what the device's SAT IR address is, just that it is one. And not a dvd, vcr, or audio receiver code.
Another thing, when in the remote menu, the word Directv is the receivers name for code 00001. And AV1/AV2 is the alternate code, either 00002 or 00003. So in this case Directv & AV1/AV2 have nothing to do with device names. Any device, other than TV, can be programmed with any SAT address code.
You could have a H20 set code 00001, then program the remote like this, code 00001 on AV2 device and code 00002 on the Directv device. The Directv device wouldn't conttrol the receiver, but AV2 would.
But now you wish to change the receiver to code 00002, with the remote in AV2 device, enter the menu of the receiver:
1. menu> parental, fav's, & setu> system setup> remote> receiver mode>
2. you will see either Directv or AV1/AV2, click whichever to reveal both
3. chose AV1/AV2, the remote will stop controlling the receiver, now slide to the Directv device which has code 00002 on it
4. press DONE and exit the menu
You see the device you start with and end with is meaningless, just the codes that programmed to them.
