I have an HR44 receiver for several years. Until the last several months, when I navigated to the PIP option, there was an "ON" choice and an "OFF" choice. Now, when I navigate to that option, it only shows the "OFF" option along with all the choices (upper left, side by side, etc). The ON choice is no longer there. I am able to click on one of the view choices, but then the receiver freezes and I need to restart it. Any idea how I can get the "ON" option to start showing again?
