thanks for the quick response. i have another question about this. to get this to work do i have to use the MP4.Dolby Vision Profile and select single stream (BL+RPU)?Single layer does not necessarily mean compressed. Supposedly the DVDFab conversion process from dual to single layer does not result in any loss in quality. Infuse will play these converted files back. The major limitations now are related to the MP4 container, i.e., lack of proper HD audio support, chapters, subs, etc.
