Just got one of these from a friend for free. He got it with a Sony computer a while back and has since gotten rid of the computer but still had the tv tuner. I know I won't be able to watch stuff with a cable card and this tuner but will it still function as just a tuner for clear QAM and unencrypted sd chanels?

Installed Vista Ultimate on a separate partition and answered my question. Yes I can use it for basic cable with windows media center.
