I am running media center to the tv tuner features and the tv guide is a like 1 or 2 hours off the actual tv schedule. the time displayed in media center and on my system are correct but the guide is off. any ideas as to why?

example.

current time:9:47
time displayed in media center:9:47
tv show on sci-fi that is airing: ba'al the storm god.
tv show the guide says is running:Black hole
