The DirecTV remotes are pretty good, but I use a Logitech Harmony One to control everything. You should probably be using the audio output of the DirecTV receiver, and use your TV only as a monitor. A single HDMI connection between receiver and processor will simplify cabling. I assume both your Apple TV and Bly-ray player have HDMI. What do you use the Apple TV for?
In my case, the DirecTV HD-DVR connects to a DVDO iScan Duo video processor that is connected to a Cary 11a audio processor (passes video unprocessed). This setup requires only two HDMI cables. An Oppo 93 connects directly to the Cary 11a via HDMI. I use balanced output from the Cary to the amps and Velodyne bass manager.
