Question / Help window capture black screen when application is full screened

[Popplars]

The title says it all.

Have performed the steps in the thread about black screen for laptop streaming.

capture works just fine when the application is in windowed mode (alt+enter)

when going to full screen the capture is simply black (pressing alt+enter to get back to full screen) (this is what I need working)

If you're trying to capture league of legends. Use game capture on the actual match, not window capture.

Not trying to capture league, I have league working just fine. I have 99% of my scenes and games working just fine for streaming, its simply this one where i get a blank screen in full screen with window capture (it also wont work with a game capture, but thats a different story and not my focus)

The game in question is Mechcommander, from the late 90's.

Then yeah, there's not a lot you can do to capture that while it's fullscreen, as I'm pretty sure it's a directx 8 or 7 game.

The confusing bit about this is that it captures just fine when its in windowed mode so why not full screen?
