I managed to record what it says and this is it.

"Darwin/x86 boot v5.0.132
3076MB memory
VESA v3.0 14MB (NVIDIA)

Loading Darwin/x86
EFI enhanced bootloader build: ToH
Using SMBIOS table found at 0x000f13e0"

After I get that message my computer re-boots on it's own. Thats the same message I get with both original and Rev 2. I've tried Nero, Roxie, imgburn, PowerISO, Sonic and just ended up wasting my blank DVD's. By the way I'm using DVD+R can that be the problem?

What can I do?
