When you choose to record a show in advance, you can change (or extend) the starting time or ending time of the show. I recently had a desire to change the 'Ending time' to make the show record less than what was alotted, only to find that I could not do this... Example.. sports show was scheduled for 3 hrs, and I only wanted to watch first two hours. Is there a way around this? Seems to me that if it lets you extend a show from 1 minute to 3 hrs, it should let you shorten a show as well. I'm guessing I can't do this, but I don't know why this hasn't been included. Anyone else ever wanted this?
