Whenever I try to open a video with mplayer set as my default video player it will play it behind XBMC. It also won't let me alt-tab to it. If I run XBMC in a window, mplayer will play the files fine full screen. It seems to have trouble taking the screen from XBMC. The XBMC screen will just freeze and I can hear the audio from the video. Stopping the video makes XBMC function again just fine.
Here is my current advancedsettings.xml, although I have tried just about every combination of settings that I can think of over the past 3 hours.
I have tried many different combinations of arguments to mplayer and also settings in advancedsettings.xml but all seem to have the same effect. Can someone please help? Oh, and in case you were wondering I am running it on Mythbuntu 9.04 (32-bit)
