Just noticed this post. It's a made by Samsung box most likely.....although I have heard there is another mfg. Actually, if you go into remote settings of the Osprey box you can setup your TV and speaker system/receiver to turn on/off as well as volume control even if it does not setup automatically, it will show you all the mfgs. I just did it recently....might be a new feature that rolled with an update. I don't remember seeing all those options in the past. I have an old Samsung Plasma, a Mitsubishi rear Projection TV and a 21 year old Kenwood Surround Receiver all working perfectly with the Osprey remote! One remote one button on and off and sound control. One note: The sound on the Samsung Plasma TV did not initially work with the osprey remote.....it did turn on and off after I set it up manually and the box seemed to find the code....had to toggle the CEC setting on and off.....and then the sound control worked magically! Another AT&T mystery feature.
