DVD playback problem

[Moemen]

Hi there;


I have a Sony Vaio PCG-F480, with a 4X DVD player. It plays Region 1 DVDs.

Now a message appears with region 1 DVD which says:
"key exchange for DVD copy protection failed"

I'm using Sony's media bar, and PC Friendly...

Any ideas?
Where can I change or edit the region settings on this thing? and where can I get the Microsoft DVD player?

I downloaded PowerDVD Player and my problem ended...
