I am also having the problem of deleting a series. I can delete the series from my listing. but, a week later I want to re-record the series again, it won't let me because it says that it will interrupt the episodes which are already in there, and they come up as duplicates from two different times of day. It then comes up with screen where you have to tell it not schedule the series. I have also rebooted my pvr a few times but these episodes are still there with recordings sheduled for a further two weeks down the road... frustrating. When I cancel a series I expect it to cancel everything. I can still record individual episodes daily as the recordings that are listed never do record.
