If you go to the project settings, there's a "deinterlace method" setting, make sure it's off.
Also, sometimes Vegas reads progressive footage as if it's interlaced, you just have to correct it. Sometimes when you right-click on the clip and go to the Media tab, you'll see Vegas imported it as interlaced, you just have to switch the field order to None (progressive). I had a similar problem once, and that's what was causing it.
