OK, I guess I am dumb as a bag of rocks . . .
I tried Daemon Tools Lite, it does not know what to do with the Blu Ray folders on the hard drive.
The file PDV8 creates looks just like a Blu Ray disk, it has two folders under the root, BDMV and Certificate. It is not an image file. Under the BDMV folder there are many directories, most of them empty, but there is one directory called STREAM with lots of 000XX.m2ts files, in this case numbered from 00000 to 00052.
When I burn a disk with Nero, I use the Blu Ray option and simply add the BDMV and Certificate folder to the project and burn.
So I'm guessing PDV8 is not creating an image file?
