Oh, sorry. I think I understand now. Well, my experience with this feature has been that the vast majority of the time it works perfectly. But in the past, there have been a few instances when it kept one or two more than it should have. Then, in subsequent recordings, it began to work as it should. I thought that if I had played back the program while it was recording that that may have confused the box, so to speak. But lately, it seems to work flawlessly. In other words, I can confirm this occasional problem, but I really have no answer as to why. It just may be one of those bugs that all devices have about them.
