The Adobe crash test dummy software lives up to its reputation again creating half blurays and then spitting the dummy. I have got rid of all my Adobe hair-pulling software except Encore and it seems it is seeking its revenge on me. Maybe Adobe/Microsoft have shares in Bluray media.
So for those who don't want the headaches, do a test burn onto a BD-RE read/write disk and if you are lucky enough for your project to work and not crash mid way then use another application to clone the test disk to a BD-R. I would even go so far as to say, use Toast and a Mac and then you won't have Gates flawed software to mess it up when you are on the home straight.
