Specs: OS 10.6.3 2.4 GHz Intel Core Duo 5 GB 1067 MHz DDR3 My MPB (Unibody Late 2008) isn't reading my 64 Bit Windows 7 disc. Is my machine only compatible with the 32 bit version? Is there a fix I'm unaware of? UPDATE: After roughly 5 minutes of trying to read. A prompt comes up saying, "You inserted a blank DVD. Choose an action from the pop-up menu or click ignore." Whats going on?
