Had a weird thing happen on my Cisco 8742 DVR twice in the last week. The box had been running 3 weeks since the prior reboot and it started being unresponsive/slow to the remote (like others had complained about happening every 4-6 weeks). But here's where it gets strange. I noticed that though the red REC light was lit on the front panel of the DVR, when I brought up the DVR recordings info with the LIST button on the remote, it didn't display the program being recorded! (Normally, it would show the program being recorded at/near the top of the list sorted by date, with the REC icon to the right to indicate it's currently being recorded). I then checked the Scheduled recordings list and saw the program it was supposed
to be recording, still in the Scheduled list (normally, as soon as the recording actually begins, the entry moves from Scheduled to the DVR recordings list). Stranger still, I decided to check the Diagnostics and saw some unusual stuff on page 1; the entries at the top for VOD stuff were in red instead of green (I don't recall exactly what the entries were, but it was something like "Stale/Unavailable") and the entries for the Bootstrapper, Network and Monitor Versions were unavailable, only the ODN version had a valid version number in it.
I waited until the show being recorded ended, hoping it would show up in the list, but no luck, and the next program that was supposed to record was having the same thing happen to it (and I noticed that several other recordings that were supposed to be recorded earlier that evening were missing too). I rebooted at that point, figuring things weren't going to get better. After the reboot, I checked the Diagnostics page 1 and the VOD info was back to valid/green info and all the software version #s were back to valid version #s. The programs that were supposedly recorded prior to the reboot still
weren't in the recorded list, but the disk percentage full had gone up a good chunk, as if all those missing programs were being included in the disk full calculation. I then noticed that some programs that I had been watching and deleted (prior to the reboot) were now back in the list, I tried playing them, but there was no playback, just a black screen, so I then deleted them, again
Interestingly, the disk full percentage didn't go down after deleting the phantom recordings. I then checked some other recordings that I had started watching that evening (again, prior to the reboot), but didn't complete/delete; they were set to the beginning of the recording, rather than where I had left off, as if they hadn't been watched at all!
The same thing happened exactly one week later; had to reboot to get the box working again. I still don't know exactly what caused it; I don't think it is time related in my case, since the second instance happened one week after a reboot, and the prior one had been 3 weeks after a reboot. I know I was adjusting the Series entries during the most recent occurrence. I had changed the Priority of one show and some details in the entries of others; perhaps, ODN got messed up in the recalculations for scheduling recordings while one of the programs it was rescheduling was actually recording? (just speculation on my part)
Anyway, it seems most likely to me that data memory in the software was getting trashed, given the missing/corrupt entries in the Diagnostics, and the missing/corrupt hard disk pointers for the recordings. I suspect that when I eventually clear off all my recordings, the disk full percentage will still be significantly above 0% and that I'll have to go through the process to clean/reformat the disk to recover that space.
Haven't heard anyone else having a problem like this. I'll keep an eye out for it again and see if I can figure out a way to reliably recreate the problem. Don't know if that will happen before the box gets the new version of ODN, but I'll try to keep you all posted. In the meantime, I called TWC; at least they gave me a credit for the missed recordings.
