I have a Directv HR24-500 receiver, and 2 RC65X remotes. I can use the On/Off buttons to turn both the tv and receiver on/off at the same time on the original remote that was installed by Directv. I just got a second remote. This remote controls both the tv and the receiver fine, except the On/Off buttons won't turn both the tv and receiver on/off at the same time. How do I program the remote to do this? I can't find these instructions on Directv's website... thanks!
