I have a solution for you and can explain exactly what is going on and needed to be done.
1 - Your DVD Rom drive has a region code (DVD rom that has a 6X speed or higher have a fixed region built into the firmware, can be changed 5 times). The fixed DVD rom like these are call RCP-2
2 - It has NOTHING to do with the graphic card in terms of dvd region, it's the DVD rom that is the big problem.
So, to get around it, you'll need to do
2 things.
1 - The harder part, you'll need to bypass/make the firmware in the DVD-Rom from RCP-2 to RCP-1 (This means the drive can be change between any region as many times as you like, but you'll still need a program to allow you to change it without the counter to go down)
You'll need to find out the type of drive you have first, go to Device manager and see the
EXACT model and make of the drive. Go to this website to find out
if there is a firmware available for it to make it RCP-1. Beware though & Disclaimer, if it goes wrong, you drive will be unusable. You'll need to flash it in Pure DOS mode, follow the instruction from the file download.

2 - The easy part, you'll either need DVDregionkiller or DVDgenie to bypass the region code. This is easy, run dvdregionkiller in the background and it'll do everything.
The
Secret option is here -
www.dvdidle.com a software that allows you bypass ALL that above and plays any region without the trouble of flashing the drive.
