Lately I've been having issues with my dvr. I'm unable to turn on PIP, when I select it doesn't do anything. I called directv customer support and the csr is telling me that its because I'm using too much of the storage space. At the time I called, I had 30% free. Now I got it to 75% free and still no dice. Any help on this will be greatly appreciated. Also when I try to turn pip, the receiver lock the remote out,only the power button works. I have to turn it off and on for it respond again.
