On another 976 Remote Control issue, I did notice that I had to push the button to change sources 2 or 3 times when switching from say, CBL/SAT to Game (TiVo to Fire TV)…like the unit did not properly read the signal from the remote. This has happened before. I am using a IR Repeater, so strength of signal should not be an issue. I sit 10 feet away from the 976, which is housed in a cabinet with a mesh screen door. The IR Receiver is mounted on the bottom of my Plasma TV next to the “Panasonic” emblem.
