I have a 722K, and I woke up this morning and found both tuners had been recording for the past several hours, and there was no program guide information past the current hour. I tried unplugging it for several minutes, rebooting the system from the front panel, and while I seem to be getting all my channels I just don't have any information past the next hour. DVR recording will be a real issue if the timer info is missing. Any ideas on what to do would be appreciated.
