I can actually read the disc just fine at securelevel 3, but I need to drop down to securelevel 1 in order to write to it (/dev/pass0 is a protected device node at securelevel 2 and 3). Is there a workaround to this, or will I have to drop into single-user mode every time I want to write to a DVD? -Nick
