Windows 7 - How to get notified of an actor, show, or keyword in the listing?

Hi there. Is there a WMC plugin or some other way or some other service that can alert me when my selected keywords appear in my guide listings? I can see two weeks of TV in my guide. I'd love it if something would immediately notify me when something like "hockey" or "wonderful life" or "marlon brando" appears somewhere in the guide listings. I used to have a set top box that allowed me to enter in as many keywords as I wanted and it would alert me when one of them appeared in the guide. It make it so easy, and I never missed something I was interested in. I have over 620 channels in my guide and it makes no sense to scan through two weeks worth of 620 channels to make sure I don't miss anything. Any suggestions? (I'd love it if WMC would do this but I am happy to use another guide service like Zap2It or whatever if thats what it takes).
