Thanks for all the info and making it clear.
Did you open the application manager launcher and get the latest patch update for PowerDVD 18 Live? The latest version is 1619.
A 3D compatibility issue has been reported and I heard that a patch was coming soon, so check the launcher for updates often, or come back to the forum as the mod posts it at the top telling you it is there.
For the crop to fill issue, I am not sure why it is not working for you. You say you are using a projector, but that is not what you are referring to right? You mean when playing on your PC or laptop monitor? "Crop to fill is for watching 2:35:1 Blu-ray movies on an ultra wide 21:9 monitor" (quote from help). It is not designed for a projection onto a wall.
