The problem has been resolved as Cyberlink support stated “After pilot checking, we are unable to reproduce the condition you have encountered. The root cause of the condition is unknown, and could possibly relate to the software/hardware compatibility, or some abnormal system configuration problems.” They asked that two folders in the registry be deleted to allow them to be recreated.
Found that in my pc where both internal and external graphics are used that a PD21/365 setup for the nVidia means that the Intel integrated graphics will not be available. PD21/365 setup for the Intel integrated graphics will have both it and the nvidia external graphics to be available.
The problem happens when the display monitor connection has to be switched from the nvidia to the Intel for PD17 to do hardware encoding for the m2ts files for BD. This connection change caused the hardware encoders not to be available permanently in both PD21/365 and in my PD21/365 Business Essentials. The solution for PD21/365 is to delete the two folders in the registry to allow them to be recreated. I did not report the problem for the PD21/365 Business yet. The same solution with different folders will probably work.
I did not have this problem in the previous PD20/365 as I edit in PD365, produce m2ts files with DD audio, author with PD17, and burn with ImgBurn. Earlier nvidia encoded files were not svrt compliant for my BDs. Later ones with a different video driver were. I prefer the Intel QS as being the most reliable hardware encoder for the job on BDs.
Hope this helps others that have both integrated and nvidia graphics and desire to use either one when desired or needed.
