WinDVD and Windows XP

[Jacksindecision]

I recently updated to Windows XP from Windows Me, and when I played a DVD in XP using Intervideo WinDVD 2000 version 3.0, I noticed that the quality of the picture was very poor, looking almost fuzzy. I was also unable to change the brightness or the color using the programs "adjustments" feature. Has anyone else seen this problem?

Here are my specs:
Pentium 4 1.8 Gig
80 gig HD
256 mb RD Ram
NVIDIA GeForce 3 256mb
16x internal DVD-Rom
