Last few days mine hasn't worked right, I can't record anything. I can schedule things still, no errors or low space or anything, but it never records. Pause/rewind still works, but the time bar at the bottom is always something between 4 and 4:30 (never the right time). Clock on the unit itself is fine. I power cycled it, still having issues, is anyone else having problems or do I need to get a new unit?
