My cable box did a random re boot and now won't open the recording files, when I did finally get to it It showed no recordings even while a program had a red dot beside it saying it is recording. There is a red light on it saying rec 1.
Try rebooting it would be the first step... Unplug the power for 30 seconds then plug back in
Give it a few minutes to boot back up, see if that corrects it
Which model of PVR?
Rebooting it again by pulling the power cord for 30 seconds is always the best first step. If you're tried that, are you able to access your recordings again?
If not, as kevinds asked, which model of PVR do you have? And does it have an internal hard drive only or do you also have an Expander?
