I have preinstall two files in your Q5II under the folder /sdcard/Android/data/org.xbmc.xbmc/files/.xbmc/userdata :
playercorefactory.himedia
playercorefactory.mxplayer

Just rename the file to playercorefactory.xml and restart. You can switch between the three player by rename the above files.

P/S: /sdcard/Android/data/org.xbmc.xbmc/files/.xbmc is hidden folder, just goto ES file explorer-> Setting -> uncheck hide system file. To rename the file, click and hold the file until you see "More" in the bottom menu then "Rename".
