I’ve tried burning both through the “Share” menu option and through Compressor itself. Both to no avail.
I’m using Memorex BD-Rs and the Pioneer BD-RW BDR-203.
I’ve made plenty of discs before, without a problem.
I just encountered another error over the weekend where I got the message “There was an error trying to burn the disc. Please make sure there is enough space on your boot drive.” There is about 200 GB on my boot drive.
