Hummm... from what I see this is a medium problem. (KEY_MEDIUM_ERROR in the log file). This can sometimes happen if you are burning too fast.
I would suggest 2 things:
- First, with CDs, you can always simulate a burning process (without writing anything on the CD): simply check 'Simulation' and make sure 'Write' is unchecked before burning the disc. Try to lower the speed if the write error still occur when simulating.
- Secondly, if you tell me that Brasero is working, please check that the writing it uses is the same as the one
Nero is using.
