Ulead Video Studio Help

[Roxnappollo]

I have recently upgraded to Ulead Video Studio Prox5 from Video Studio 10. For the life of me I cant figure out how to change the preview window in ProX5. Im not sure why, but in the preview window there are black bars on the right and left side of the video that show up in any video I make in the program. If I do the same thing in Ulead VS 10 with the same video and the same music, the black is not on the video, so it must be the display in ProX5 right? Anyone else use Ulead or have similar problems with thier displays and know how I can change it? I ave gone through all my settings in the program and I just cant find it. I was gonna post some video to show the difference, but even though there were obviously different when played in windows media player, when I posted them to youtube they looked the same. :l /sigh This is all so confusing sometimes. Here is what it looks like anyways.
