Query: DVD isn't recognized on either of my MACs.

If I insert it on the I-MAC it says I inserted a blank DVD. If I try to do anything it locks up the MAC. On my MAClaptop after a minute or so it ejects the DVD. Returning the disk to ASPYR. So is the game any good? Don't know can't even load the thing.
