ElDiabloConCaca if you stop buying Apple products I think the company may go bust:)
I only have a itouch and MBP so some way to go to catch up to you.
But for what its worth I agree that it sounds like your optical drive needs replacing.
Not sure if this helps anyone. I made this mistake..... I was using a blank dvd thinking it was a cd. User error. The server I was making the boot disk for (on my MBP using Disk Util) only boots from cd's ( not dvd's).
BTW: I was unlucky as my dvd box had a cd front sheet. But still should...
