Open Broacaster and PR:BF2

[cribbaaa]

I've been using OBS to stream PR:BF2 to Twitch for a little while now, however in order for OBS to grab the image from the game I need to remove the capture source and add it again every time I start PR, otherwise I get a black screen.

Is there any way to get around this? it's a minor annoyance but every now and then I forget to fix the problem.
