Comment 3 for bug 316248

i am pretty sure if you try as root there will not be any problem !

burning operation is a typical costly operation( writing to a block devices is slow ) .
Also it's kinda real time operation as buffers needs to be flushed immediately(reading from the file and flushing/burning
to a cd)so the process requires higher priority at any cost which is best done by a process started by root .

so in my view if you do that as root , like sudo k3b and then try the burning operation it should work.
