Partial solution.
I've added a new device "Dream Box (Network Control)" controlled by the "CORE".
I've changed a little the device template->Ruby codes.->Process Inizialize.
I've inserted a dirty ruby line
system xine http://192.168.0.12:31339/0,0101,0201,0294,0295,0081 --fullscreen --no-gui -B"
Saved all. Restart all.
Now xine starts while orbiter is loading and hide itself somewhere. Process is running and audio is coming. Find the video is more an adventure.
Have to go to "Live TV" and then press CTRL+1 to get the correct video window.
Other solutions?
