I have had identical problem and I don't see how old this is but I run 2 burners and the first time Microsoft fix it fixed the burner go to fix it site and run the one that's specifically for that problem repair burner paths.now the second time it turned out that the cable running to the burner was bad.right now I have one that wont open unless theres a disk in and have to use paper clip open manually and leave a disc in,cause its the burner is bad.but works fine otherwise.can also remove drivers and reboot and os will auto reinstall and redo paths.
