Onkyo TX-SR503 (receiver) remote code

[treaders]

Hello,

Does anybody know what the remote code is for the Onkyo TX-SR503 (receiver) remote to control the DirecTV HR20-700 HD DVR?

I have tried a number of the remote codes in the Onkyo remote control codes listed for DirecTV but I have not been able to control the HR20-700 using my Onkyo remote yet.

I primarily would like to be able to turn the HR20-700 on and off using my Onkyo remote.

Thanks,
treaders

D* gives 2 different Onkyo remote codes. I had to use one to turn the receiver on using AV1 (must push power button twice) and the other code using AV2 to turn the receiver off (must push power button twice)
