Ram, what you want is the "Copy" products. (DVDCopy, BlueRayCopy, UHDCopy)
The current version is DVD FAB 10
DVDFAB 10 is a generic name, much like Microsoft Office is generic.
Inside DVDFAB 10 are different "modules" such as DVD COPY, BLU-RAY COPY, and many others.
If you owned a lifetime copy of DVDFAB 5, that should unlock DVD Copy and DVD Ripper
You will have to buy BLU-RAY licenses if you want to rip blu rays, but you'll be able to try demos of those modules first to see if they meet your needs.
As far as movie server goes, it seems DVD COPY and BLURAY COPY are the best tools for making files that work with Movie Server.
While it's true you're creating an ISO file, there is also one more file generated by DVDFAB10 BLU-RAY copy - a small text file with a description of the movie, which DVD Fab uses to display artwork. I don't believe this file is generated if you use another method such as passkey.
Additionally the Copy modules in DVDFAB10 have a very convenient "Save to DVDFAB MOVIE SERVER" which makes ripping movies to your server nearly as easy as "1 Click"
