DVD movies:Blocked image after driver install

Hey, I took some time to delete my geforce drivers last night, used Detonator R.I.P and Detonator Cleaner just to be safe due to cruddy MSI drivers that were not deleted when I tried installing nVidia drivers.

Anyhoo, now my problem is with watching DVDs with PowerDVD. When I hit play, I can hear it playing, but the image is blocked with what seems to be a black box. But I can see the video playing in the window by looking at the sides because there are two thin stripes of what the video is playing. I took a screen shot of my desktop to show what it looks like.

the two thin blue stripes in the DVD window is the video in play, but the black box is in the way... If I move the Window around quickly, I can see the entire video playing as if it were a shadow on my mouse cursor trail....
I tried installing the GeForce drivers again, PowerDVD, WDM drivers, nForce utilities, just to see whether i mistakingly deleted some needed DLL file or something, but to no avail. Any ideas?
