The message that auto-extend will continue the recording of a world series game (that is present on every NFL and most college football games) is gone. Is this a feature that MLB doesn't allow? That seems ridiculous.
Update: I had manually set the recording for Game 2 to 1 1/2 hour beyond scheduled stop time (which would be total time of 4:30), but lo and behold, the game went 4:40 total time and the DVR recorded it all. It appears it does auto-extend even though it doesn't say so.
