Sounds like the registry is messed up.
Create a manual restore point as a precaution.
Uninstall all Power DVD14 (and any other Power DVD products, but if you're running DVD14, there should be nothing else)
Choose to uninstall your personal settings _ it will ask you if you want to save them _ choose not to.
Now go into "Documents" and right click on any Cyberlink folders there to delete them.
Also look for a folder that Power DVD14 created for your 10GB of free storage _ delete that as well _ there may be one in "Computer", "Pictures" etc _ get rid of everything.
Install CCleaner and run its registry cleaner as many times as necessary until it finds nothing. There will be lots of stuff to delete too other then left over Cyberlink remnants.

Use the free version.
If you're worried about deleting the registry files that CCleaner finds, it will create a folder to save them in _ you may do so if you wish.
Restart and run CCleaner again _ repeat this procedure until it finds nothing.
Now download you upgrade file of Power DVD 14 to the desk top and install it form there and at some point it will ask you to enter a product key from your previous installation _ use your Power DVD 9 key here. Continue and it will ask you to activate Power DVD14 with your upgrade key.
Restart and load one of the problem Blu-rays automatically, let DVD14 do it on it's own _ give it some time.
Power DVD has the habit of selecting itself in AutoPlay to play Blu-rays.
If there is no option to enter your key from Power DVD9 to do a clean install with an upgrade key, then you will have no choice but to install DVD 9 and then install DVD 14 on top of that.
It should work this time around though because you have deleted the Cyberlink file(s) in "Documents" etc. and cleaned up the registry.
