I got the “code 6” error, downloaded the fix in the link, and it solved the problem. I am working on a “PC” in Parallels, using Toast to burn a BDMV folder.
On a side note, as of today, 8/17/08, Adobe still hasn’t fixed a bug in Encore that makes button “selected” states invisible. Meaning, you can’t see what button is selected- no highlight. There is currently no workaround. This bug only applies if you are using 16:9 footage on a Blu-ray project on a Mac. This is what forced me to have to use Encore for PC.
I’ve found both versions to be highly unstable, but I am finally able to deliver a fully working BD, menu and all.
