A friend bought a brand new PB and tried burning a DVD with toast and got the following error when writing the lead-out (at the very end of the burning process). Does this mean his superdrive is malfunctioning and should be replaced? Thanks!
Just to rule out a hardware error, ask your friend to run the hardware test cd that came with the PB.
Just got the same error today (on a PB 12") while trying to move some videos to DVD using Toast. After a failed burn at best speed, I tried it at 1x and the same error occurred. I then just saved the project in disc image (.toast extention) and restarted toast. I then just used the image to burn it to a DVD and it finally worked. Hope this helps.
upgrading your toast to the latest version should also rectify some incompatibilities with some dvdr media...
