Windows thinks my macbook pro is a macbook air?

I recently installed Windows Vista on my Macbook Pro using Bootcamp. When I put my Mac OS X Leopard DVD in to install Bootcamp on Windows (all the drives and everything) but it constantly ejects the disk. After about 15 or 20 tries it will finally work and it auto plays and I click "setup.exe". But instead of the Bootcamp installer opening, it gives me options to install something called ShareCD/DVD (or something like that) on my "Macbook Air". Is there anyway to fix this? Thanks!
PS: Everything on my Mac was updated and backed up before partitioning the drive. I made sure I did everything right - the partitioning, formatting, installing. I just can't figure this out

If a thorough clean of the discs surface doesn't get bootcamp going your OSX install DVD is most likely faulty like my original disc was when I first tried to setup XP on my uMBP. It's a hybrid disc, with a HFS partition for OSX and standard CDFS where Windows detects the bootcamp installer - it's that part of the disc has a fault.
