There was a power surge on Rogers Friday around 5PM. Internet access was down for about 3 hours.
When I checked my DVR, all of the "all episode and timeslot" scheduled recordings were gone. The "one episode" ones were still there. I programmed them all back in and it seems to be fine.
I don't know which areas were affected, but make sure you check the scheduled recordings in your DVRs.
Luckily, I keep a list (spreadsheet) of my "usual" recordings/channels/times, etc. So putting them back only took about 5 minutes. Weird that only the "all episode and timeslot" recordings were affected.
