Okay, so this is a scenario that's happened to me multiple times with NextPVR:
1) Channel Foo says that Episode 4 of the series "Bar Bar" is going to air on November 1, and Episode 5 is going to air on November 8. I have a recurring recording set up, so I expect it's going to record both episodes.
2) Something happens, and "Bar Bar" doesn't air on November 1 after all. NextPVR still records something in that time slot, but it's not what I wanted. So I delete it.
3) November 8th comes around, and Channel Foo is airing Episode 4, the one that got postponed last week (the schedules have been corrected). I expect that my recurring recording is going to catch it, but IT DOESN'T. Because NextPVR has a record which says "Oh, we already recorded Episode 4! So he won't want us to record it AGAIN!"
Here's what would solve the problem (correct me if I'm wrong): An easy option to Delete a recording in such a way that NextPVR DOESN'T think "this episode is one we've already recorded." This could also be useful in cases where it wasn't a schedule change but just an unwatchable recording (the channel was having technical difficulties so what recorded was unwatchable, etc.) It doesn't seem like it should be that difficult!
