-I was able to see my pictures in full screen and even in slide show but now nothingh but a black screen.
all thumbnails are ok dow.any clues what is my problem, even tried to switch to the default skin with no seccess.

-I just identified what was the diference, If I start MP in full screen mode on the secondary monitor(TV out) I am unable to see my pictures in full screen. How ever when I start it in window mode first than go to full screen mode from now on the pictures will show in full screen. this is defenitly a fix that should be made for future releases.

-Ok I got the pictures viewing back with this methode but I lost with stability.If I do that, starting some other aplications in my case (MYtheatre) the MP screen is replace by the wallpaper,I click on it (on the TV) I still hear MP defaults sounds but the interface is gone and some times it just revert to minimised on system tray.Weird!!! I know that MP due to it's relation with direct X is not known to work well over a secondary monitor unless it is set as the primary monitor but if those inputs can help it's developement.
