After re-installing MCE I had a similar problem. Dell sent me PowerDVD cd and after installing hap no problem playing DVDs.

Have you tried uninstalling and reinstalling the software?

Other than that I have no clue. I'm sure some of the more savy members can be of greater assistance.

I'm gonna try it again. I am using a cd that did not come from dell. Its a power dvd 5 cd. Does the version matter? What version did dell sent you? Thanks

I don't see why it would matter. Dan't have the CD with me and not sure what version it is, but it is a dell CD that only runs on dell machines.

Hope the reinstall helps...
