Any of you guys wanna see my very successful program WinDVD Tweaker 2.8

http://3dgamer.tripod.com is my site

I am nearly finished 2.9. I am building into it the ability to auto change the region of WinDVD to match the disc in the drive but I am stuck and I hope you guys can help me. How do I get region info from a disc. Surely some of you guys must know!
