How do I get hd dvds to play on my windows xp OS?

I have searched and no questions reguarding this.

When I had vista, it ran my hd movies just fine.

With xp my hd dvd drive reads the dvds just fine, windows sees them as dvds and of course runs them.

But, when I pop say a hd dvd (king kong) or patch adams. It doesn't show any movie, anydvd says it's scanning my movie but nothing pops up. I just want to see what my movie looks like on my new 1900x1200 (1080P) pc monitor lol

My specs :

Xp is 32bit
Ram 2 gbs
GPU 8800, so hd output shouldn't be a problem.
Processor e6850
Dvd Drive , HD Drive

Im hoping if I can download an update it can read hd dvd movies. Thank you for your time.

 

Do you have the Codec install to play the hd dvd movies ???

 

You need to make certain that your video driver supports the HDCP standard. We know it did in Vista, it might not in XP. XP SP2 Is also needed.
