Yes, I HATE that! I routinely add an extra hour to the recording time and sometimes that's still not enough. I watched a recording of a UCLA/Arizona game the other day, where on a whim, I had added an extra hour and a half. Thank goodness! There was a walkoff home run in the 10th. The game ended with only a few minutes left to spare in the recording. The rebroadcasts are safer, because they will end on time, but they stink, because the editors will just blindly cut out huge swaths of the game.
I had only set mine for an extra 1/2 hour. . .not happy. . .missed the end of the LSU game, but I went ahead and stayed up to watch the replay at midnight. I am paying for it today.
It seems that there has been quite a few this year that have gone over.
