Media center dvd menu not working

Hi all, been awhile since ive been here but Microsoft is pissing me off again.

I just installed windows seven on a new htpc and everything is now working like it had before with vista.

Only problem is media center, when playing a dvd it makes me watch all the godamn trailers and adds, the dvd menu key does not work. Chapter skip didnt work either. I was force to watch 15 minutes of crap on the Sherlock Holmes DVD.

How do i repair this to never happen, screw the adds!?@?

Thanks for any help ahead of time.
