PC-Based Digital Cable Decoder Hack?

musicbadger asks: "Hey, I just got one of the ATI All-in-Wonder Radeon cards and it is pretty good. It has a 125 cable-ready tuner on the back. I have an IRMAN which allows me to change channels with a regular remote. The AIW allows me to record shows, as well as pause/rewind live TV. But it only tunes in the basic non-premium channels. Shouldn't there be a way to use the same decoder algorithms used in the hacked cable boxes to decode premium channels using the computer's CPU? Of course, I would still pay for the premium channels, this is just a way to allow me to "time-shift" them using my VCR of choice." I think it's high time that decoder boxes had an external input to allow it to be "slaved" to another device. This way, such hacks would be unneeded. What say you? If such devices do already exist, where can they be found?
