Hello, For a couple of days now I can't watch the shows I have recorded on my DVR. I get a message saying they aren't available. (Less than 50% of DVR space is being used). Also, my remote won't pause, fast forward or rewind live TV for a couple days either. The remote works otherwise (for power, volume, channels, etc - and I did change the batteries just for the sake of trying). What could be wrong? Thanks for any help!
