Hi Arcx,
I'm sorry to hear about your issues with playing Blu-Ray(TM) disks. I will begin setting up the system and attempt to replicate the issue. I will let you know my progress as I get more information.
In the meantime, please use one of these links to download a previous driver so you can watch at least some of your movies again.
Here's the link for 32-bit: Intel® Download Center
Here's the link for 64-bit: Intel® Download Center
Could you also let me know if you've tried downloading the latest driver via the Intel(R) Download Center instead of Windows Update? Also, are you getting some sort of error message when attempting to play the disks?
Regards,
Zack_K
