With qualifications to my answer, yes... DVDfab will burn BR disks... BUT
Currently, only disks made (released) before June, 2008.
They are working on the new BR+ protection, but no firm date has been set for release. Have to make sure it works, and get all the bugs out... not easy to predict, as one never knows what problems one is going to encounter, or how long it will take to overcome an unanticipated problem.
