Ok what I'm looking for is a way to (not sure if this is even posible, but I would think) discramble cable tv through a cable modem.

the reason I'm asking is because I have cable modem and TV but I want to be able to watch cable through my pc, and since I don't have a Video Capture card and dont see having the money for one in a long time i was hoping someone would be able to come up with a way to do this.

also I would think it is possible to do so, because of the fact that the signal come through the same wire. but that's just my thoughts.
