Having problems playing DVD's on my XP comp

[hecklernumber1]

Hi,

I recently rented a few dvd's and tried to play them using everything from PowerDVD, Windows Media, Ulead DVD Player, and RealPlayer unfortunately they won't let me play. On I think the RealPlayer and the Ulead Player it says because of Macrovision protection, or something like faulty Macrovision distribution.

I used to play regular Macrovision protected movies on my computer but I can't figure out why they won't work now. The only thing that has changed is that I downloaded the new service pack for windows. Could this be my problem?

Have you reinstalled powerDVD?

You might need to.

not since i've downloaded the service pack, but I have updated my media player to series 10

I would try to reinstall powerDVD.
