I have just used template 9* and have burnt a 3D-BD.
I see you mention reports on 9 & 10 "The authoring progress went wit that project to 77%, and then did not contiue" and "Using another 3D template, template 9, with the same result - beside the detail that it ended with 88%. "
Since the authoring process is the conversion of the media data prior to writing to disc, I wonder what you have that is causing the problem. I'll test the menu's first and see if 1012 is ok with my 3D mp4's. Then I'll go in and use your sample media (thank you for providing those) and replicate the template burns and see if I can duplicate the authoring issue..
*Template 9/10 are the default 3D menu template provided with PD10.
