In the last couple of weeks my receiver has started freezing. It is an HR-22 100. It first happened when it was almost 90% full. I dumped stuff to get it down below 50%. It just freezes, with the picture. No error message and will not respond to anything but the red button reset, which seems to fix it for awhile. I think it is happening during recording because I have yet to have it happen while watching live TV (not that I watch a whole lot of that FWIW). It just now happened while recording a movie. Quite a few of my recordings have had long freezes in the program. If I wait, sometimes the program will start going again. Sometimes, I guess I don't wait long enough. I've had the receiver about 4 years and I think this is my first major issue. Oh, and after the RBR, the program banner comes up a couple or more times and I'm looking at a black screen. Any advice, guys?
