I guess Dish figures that the extra minutes won't matter that much, since those recordings will be deleted after eight days (or whatever number of days you set it for) if you don't save them, so the extra minutes do not take up much hard drive space. Also, it helps make sure that you catch the end of the program if it runs over by a minute. The only time the extra minutes for PTAT become a PITA is when it causes you to max out all three tuners on the older Hoppers, so you can't record or watch anything else live in that time-slot until after PTAT ends.
