How can I make my Sony Laptop VAIO Z-series read Sony Blu-ray Disks?

I bought a laptop from Bic Camera in Tokyo and I was ured these Sony BD-R blank disks (Ver. 1.3) would work on the Matshita BD-MLT UJ232AS drive that comes with it. Well, that claim is false: my windows vista ultimate is saying it cannot write to these disks. I tried to return them, and surprise surprise, they forgot the English with which they convinced me the disks would work - one of those common overnight bugs that seems to strike whenever one of us white people walks back into a shop holding recently purchased merchandise. I have searched the internet for some drivers or anything to make them work (I paid over 100 bucks for them, and don't want to just throw them out) and found nothing. Is there any software I can install, perhaps a driver or an application to make them work?
