The feedback window

[Recon]

The most recent time I installed GKnot and rendered a movie, now I get this VirtualDubMod Feedback Window, which shows a live representation of the rendering in progress.
At first I was like "wow, cool!!" but now I noticed it cuts my framerate in half.
How do I make the feedback window NOT show up by default?

Thanks.
