Hi, I am trying to integrate the Zidoo Blu-Ray Menu Player ("com.zidoo.bluraynavigation" ?) into ZDMC's playercorefactory.xml to have the player as an option when playing ISO files using the menu option "Play with...". I tried the following, but that doesn't seem to work. The external player won't start and the focus returns to ZDMC immediately. Can somebody help? Here is my playercorefactory.xml that I put in the userdata folder: <?xml version="1.0" encoding="UTF-8"?> <playercorefactory> <players> <player name="BluRayMenuPlayer" type="ExternalPlayer" audio="false" video="true"> <filename>com.zidoo.bluraynavigation</filename> <hidexbmc>true</hidexbmc> <playcountminimumtime>120</playcountminimumtime> </player> </players> <rules action="prepend"> <!-- Zidoo native player rule--> <rule name="local" filetypes="iso" player="BluRayMenuPlayer" /> </rules> </playercorefactory> Thanks in advance for your help!
