[DVR] Rescheduled episode warning
Due to the hurricane, several shows were rescheduled last week. If you have a series recording for it, and the guide was not updated in time, the DVR will think it's already recorded it. It will then not record the episode, even if it's marked NEW (at least for A28).
I noticed this with "How I Met Your Mother", which was not scheduled to be recorded. I had to manually tell it to record. You could try slogging through the history and deleting the original entry, but that may or may not help.
