TimeSkip, follow these steps to get a bluray movie on your hard drive to play as a mounted drive using DVDFab's virtual drive ...
1st, DL Fabs virtual drive 1.2.0.0 and install it.
It will make a virtual drive at the end of your drive letters. In my case, it's drive T.
To play a movie ripped to the hard drive, make sure you choose to make a miniso file when you rip it. (If not, see thread I mentioned above to quickly and easily make one.)
Start DVDFab virtual drive.
(It will place an icon down by the clock.)
Right-click on the DVDFab virtual drive icon down by the clock.
Select the default drive letter in the pop-up window. In my case it is drive T.
Click on "mount"
A navigation window will come up. Go to the wanted bluray movie folder and select the .miniso file.
A window will materialize showing the BDMV & Certificate folder. Minimize this window.
Launch PwrDVD9 (or 10) and click the play button. The movie will now play!
I have had great success with this method playing bluray back-ups on my hard drive and playing them with PowerDVD 9.0.2320.a I don't see any reason why it won't work with PDVD10. If it does work, please post for others to know! Thanks
