NFL Sunday Ticket games can only be recorded in 6-hour blocks, even though the games last only about 3 hours. If I record two Sunday afternoon games -- something I do often -- the long recording time makes it impossible to record early evening shows on other channels. There are options offered to extend recording time, but no option offered to shorten recording time. Is there some way to do that? Is DirecTV working on that capability, or maybe offering NFL games in 4-hour blocks instead of 6-hour? A premium-priced service shouldn't be this difficult to use.
