lost video out capabilities

Hi ya'll

I have a G5 dual 2.o running tiger and FCP studio. I also have a decklink hd pro installed. When I first launched Soundtrack pro I was able to output video through my decklink card out toan external monitor. After playing with a couple of times now it won't work and none of the other options like Cinema Display work. I am at a loss. I've trash my FCP preferences and even reinstalled ST pro to no avail. Are there ST pro preferences aside from the normal FCP preferences?
Any help would be greatly appreciated.

Joe,

I had the same problem. I'm running just STP on a 1.67ghz powerbook, and the first few times, I could display full screen video on my external monitor. Now none of the options seem to work for me either. Although this is less of an issue, because I use the external monitor for other things (video window and mixer 'faders'), something definately seems to be off.
