Right,my comp came with a separate TV card (haupauge essentially a tv tuner which has it's own tv cable attached). Basically I plugged a 3-way splitter into the tv cable. one goes to my regular tv, one to my router and one goes to the tv card. That way I can watch/record my regular cable program through Windows media center
Only disadvantage: the recordings are in .wtv format (under Vista it was .dvms or so)
So you'd need TMPGEnc to cut out commercials but others than that it works just like a programmable VCR
But to be honest, I rarely watch TV anymore.Too much cr*p, too many reruns and WAY to many commercials.
