Sometimes the guide data shows that a program lasts for a half hour or an hour but in reality it is consistently much shorter, and then the channel pads the remainder of the time slot with ads, promos, short features, etc. It would be great if you could specify a maximum recording time in such situations. So, for example, if a show begins at 20:00 and you know it will end by 20:20, you can specify a maximum recording time of 20 minutes and the recording will end at that point. Note it should not count any pre-recording padding in the maximum time because that is typically before the program actually starts, so if you counted that it might chop off the end of the program.
