It is common for some of my timers to stop recording just before the end of the show. I have edited these timers and added a minute to the stop recording time, but it doesn't seem to make a difference how much I adjust this or how many minutes I add--it still stops early. Do any of you have this same problem? Is there a fix? The "Big Bang Theory" is one but there are others. I don't use PTAT since there often are a couple of weeks between recording and viewing.
