If I insisted (“Continue”) the DVD-RW would immediately give me an error and stop. The DVD-R disc I tried will eventually give me an error.
There is no visible clues of anything happening after “Check again” is pressed.
“Quit the other applications” essentially restarts X and the problem persists.
The problem persists after reboots and permission changes.
Any help would be appreciated.
