I've tried burning an image file [authored in Spruce Up] using Prassi Primo. I've only tried it on a dvd-rw and a test on a dvd-r first until I've worked out how to do it properly.

When it gets about half way through the burn, it spits the disk out and comes up with this error:
Image Job ...... Terminated with errors.
Error -10 at Sector 1207584 - Command :2A Sense:04 ASC:08 ASCQ:01

What is this about? What am I doing wrong? This is really frustrating.....!
