You may have read my previous thread in regards to program scheduled for recording not showing up in the "recorded programs" list. This has even been the case when the red light on the front of the unit has showed it was recording. My question...do these "ghost" programs still take up space on the hard drive, and if so, how do you regain that hard drive space?!? Right now if I add up all the time-length of the recorded programs, I show approximately 28 hrs of recordings. However, my 100 hr. unit only shows 58 hours remaining...so it thinks 42 hrs. have been recorded. I realize there is probably an hour buffer for each of the TV supported by the 522, but even then I still have approximately 12 hours of unaccounted recording time?!? Any ideas?
