I have a 622vip and can't get the picture in picture to work. Here is what I do and maybe someone can tell me what I am doing wrong. I turn the receiver on and put it to channel X. Then I turn it to channel Y. When I hit the "return" button on my remote, I can go back and forth between X and Y with no problem. But when I hit PIP, expecting to get X and Y on the split screen, I get some other channel. I get X on one side of the screen but I get some other channel (not Y) on the other side of the screen. Something is wrong but I don't know how to figure it out.
