If the only player that shows up in your 'play using' tab is videoplayer, then KODI is not recognizing your playercorefactory.xml.  The file itself looks fine.  Either it is not in the proper directory,

C:\Users\YOURUSERNAMEGOESHERE\AppData\Roaming\Kodi\userdata\playercorefactory.xml,   It's in the correct directory

playercorefactory is not spelled correctly, It's spelt correctly 

playercorefactory.xml.txt is what you have which is not correct, and should have an edited file extension so that it is playercorefactory.xml exactly, This is correct

you are not using an official build of KODI, Defiantly using an Official build

or KODI is somehow broken and will not recognize the file.

Link your C:\Users\YOURUSERNAMEGOESHERE\AppData\Roaming\Kodi\kodi.log somewhere so I can look and see if KODI recognizes your playercorefactory.xml.  Alternatively, you can use the built-in log function for KODI.  Do not post the log here.

Hi brezen1, Link to my kodi log thanks for taking the time
