I searched this topic, and no one else had my problem. So, I've come to the conclusion that I'm incapable of using this feature. Here's the issue: I turn on the TV, and it's on say ESPN-HD. If I manually input numbers to another channel and go to say, RAVE, if I hit PIP to see what's on ESPN, the PIP does not show ESPN, but say DISC. I go back to ESPN. I've tried going back to it by putting in the numbers 92xx. I've tried hitting recall. I've tried by going back via the EPG. None of that works. It just seems like at some random point, PIP decides what channel it is on. I really don't know what I'm doing wrong. Can someone clue me in?
