Can Procaster capture only media player sound?

Hi. I'm currently running dual monitors: one screen to do all of my work and browsing and a second screen for the channel (so I can see and control what's streaming). I use MPC as my media player.
Now, I want to be able to stream while playing games and not have the game's sound interfere with the stream while I am streaming a video (in other words, my audience won't hear me playing video games while I am streaming a different video to the channel. Only I should hear the video game). Is this possible with Procaster or would I need a soundcard or program?

Procaster can't selectively choose different desktop audio sources. You'd have to use an additional program such as Virtual Audio Cables.
