Using a JP1 programmed remote to control HR20 and HR22 DVRs

I posted the following at www.hifi-remote.com/forums but am also asking if anyone here can help.

I have a 9910 which has worked quite well to control an H20 DirecTV receiver and HR20 DVR. I just changed the H20 to an HR22, and I would like to control both with the 9910, but I cannot get it to work.

I program the 9910 with a JP1 cable using Keymap master. I had downloaded from the hifi-remote site a file for general use with an HR20 DVR. It stated to set the raw fixed data to C3 and that a second receiver could be controlled by setting the receiver to "AV1 or AV2" and then setting the raw fixed data to D3. I did this for the H20, and it worked fine. The problem is that neither the new HR22 or original HR20 will respond when they are set to AV1/AV2 instead of DirecTV.

One difference appears to be that the DirecTV remote could be set to code 00002 on AV1 and control the H20. This code apparently does not work with an HR20 or HR22. Remote code 00003 is the only one on the DirecTV remote which will control an HR20 or HR22 when set to AV1/AV2.

Does anyone know how I would program my remote is the code for the HRxx is 00003? Is there another protocol, or can I set the raw fixed data to something different from D3 so I can control two HD DVRs?

Thanks for the help.
