Clear QAM | Make HD Box Sets of Your Favorite Programs

I am in the process of switching over to capturing shows via Clear QAM. I currently use an indoor antenna and an ASTC tuner card but the reception is just bad enough for me not to want to record anything. Some days the reception is good, some days it is pretty poor. Such reception is fine for the occasional televisions watching but for some reason the occasional stutter really bugs me on a recorded program.
