Jim, no reason to apologize. Your app is awesome. We did our 24 hour gaming stream on Twitch last weekend and used obs exclusively. It worked great. The only two issues we had (besides our own problems!), was I used dxtory for Killing Floor, and for some reason Kag2d (
http://kag2d.com/en/) had a flickering black screen while one of our guys streamed it. Didn't flicker too bad, so we just went with it.
One thing on Killing floor. I had tried windowed mode in KF, and window capture in obs. Didn't work. But what is odd, is whenever I tried windowed mode capture, and then deleted that window source, and created a game source connection in obs to killing floor, the game source would work as long as I didn't close Killing Floor. Very odd.
<edit>
I should note I just discovered this work around to getting game capture to KF to work. Sometimes it is tough to do, but once the game capture takes, it is much better than using dxtory/obs.
