Hey Guys,
I was just trying to write an ISO9660+JOLIET cd and I got the "Reason: Cannot Write Medium - Incompatible Format" error. It wouldn't let me burn a CD. I tried adding this answer to a post with this title (http://forum.imgburn.com/index.php?showtopic=6920), but it wouldn't let me, so I wanted to add it here so that people know the solution: I had added a custom write speed of 12x. When I removed it, it worked fine. This was on a Sony Vaio Z series Z11WN/B laptop. I know google brings up this forum, so I hope this helps someone out.
Kind Regards,
