Media Center

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

never mind.....it fixed itself.

new issue, when i have media center expanded to full screen, I and move my mouse to the second monitor. it locks it in as if it was a full screen game.
