@ ARAMP1 , You probably already know & do this .
You can have several versions of DVDFab installed on the same OS.
I have versions 7 through 10 installed.
I even have the very old version 3 HD Decrypter installed.
They never seem to conflict with each other.

Yes, I have 8, 9, and 10 installed. Lately, I seem to be having problems ripping bluray disks in version 10. Normally, the disks will rip at 15-25 FPS and produce a good copy. Lately, with version 10, I'll know right away that the rip won't be successful when it'll start reading the disks at 100 FPS. DVDs don't seem to be affected. I'm sure there's a setting in version 10 that needs to be adjusted. But, I've been using version 9 without any issues.
And, of note, the movie rip was successful and plays just fine in Plex. I'm just wondering why some MP4s will complete and allow adjustment of the properties (making it easier for Plex to find the metadata) and some won't.
