I have an 8800GTX . And I now have, I believe, a hybrid BD/HD DVD player. I'm going to do some more testing and make sure everything is still working correctly, and then I'll document the entire creation process and how it all works together. It's not exactly the most intuitive system but I think it works! I'm not trying to be a tease, it will likely be Monday evening before I can have everything up. So if you want to try it yourself, then here's what you need:
The Japanese WinDVD release with patches
Altiris' Software Virtualization Personal Edition (free)
XBox HD DVD drive
Blu Ray drive
HDCP compliant video card
Fairly beefy system or a card that can handle the decoding
Use the Altiris software to create virtualization layers of both the HD and BD versions of WinDVD. Activate whichever layer you require for the disk you want to play. It worked for me with the HD DVD drive, and based on that it should work fine with BD. I'll be able to tell you for sure on Monday evening. Is it cheap? Nope. But having a hybrid player feels pretty good.
Here's a link to a post describing how to order Intervideo WinDVD 8 with HD-DVD/Blu-Ray support.http://www.avsforum.com/avs-vb/showt...&&#post8871286

Thanks Microsoft & Toshiba!
So in theory assuming one had all the compliant parts already the HD-DVD addon drive for Xbox 360 is the drive to buy for PC as well! WOOHOO!
