Hi,

This never happened when I first installed vista but then it used to come up every now and again and now it seems to happen all the time.

The error message i get when playing a dvd in windows media player is:



I used to be able to solve this by restarting but now I restart and it keeps coming up.

I also get this message when i use windows media center:



And when i try to play it in windows media center the resolution of my screen goes right down

My computer spec is:

Windows Vista Ultimate 32bit
Intel Pentium 4 CPU 3GHz
2GB Ram
ATI Radeon X1650 PRO : 1280:1024

Does anyone know whats going on? It never used to show this message but now it appears all the time and I do not know why!
