I recently setup an MX-900 with MRF260 to control several devices, including a Directv HR20-700 box. I am able to control the HR20, but occassionally the Directv changes channels on its own, sometimes brings up the record banner on its own and am told sometimes locks up. Of course my customer says all this is a result of the new remote. I don't have much experience with the Directv box, but I don't see how the remote could be issuing commands without pressing a button.

Some additional information. The directv had been setup for RF, so I had to reconfigure it for IR. Now the Directv remote no longer works, which the customer is also complaining about. I currently have line 1 from the 260 wired to the IR reader on the Directv and this channel is set for RF only on the MX-900.

The customer is telling me to pull out the MX-900 setup and wants to go back to the Directv remote, so I probably have 1 chance to try and make the URC configuration work. I appreciate any suggestions.
