I transferred all of my shows from my two 722 receivers to their respective external HD. Now, on one drive, I'm having a hell of a time watching anything from it. The shows are there but you cant delete them and when you click watch, nothing happens. Now, this morning, for whatever reason some shows started working. I transferred them off and others that it would let me. I don't know what the cause is or if I did something to make it work. It's really flaky. I've unplugged and reset the hopper and all and nothing seems to be getting me access to the shows on that disk. Any tips n what I can do?
