"can't Mount Cd Image" Error

When I attempt to install openSUSE 10.2 on my computer, I get a red message box with the error "Can't mount CD image". I have tried to load different drivers, but am not entirely sure what I am doing. I just bought a laptop with Vista pre-installed, and got a blue screen on first boot up. So I am installing Linux on my desktop so I can learn about it before installing on my laptop.
I am attempting to install via the DVD version, if that has anything to do with it.


My computer specs are as follows:
3Ghz Pentium IV
256Mb ATI x1600xt
ESC PF4 Extreme motherboard

Thanks for your time!
