As for my inability to choose something other than "dust" or keep it from giving me the random lines, I've always assumed the effect was just like that. Or that I had a bad install of the program, which doesn't seem very likely given that I've had this problem after multiple reinstalls and even before upgrading from Vegas 8.
No, I can turn those off completely. I still believe you have something other than Dust allowed on some of those keyframes, but whatever ^^
There is a bypass you can try - add a timeline over your whole project, place an Empty Event on it and place the Effect on it - should make the effect work for the whole project.
Btw, was just trying it and noticed that dragging a Reset To None effect to that makes some dust and a single scratch appear - they disappeared after I pulled Grain and Tint sliders to the top and back, though and didn't reappear even after playing the video.
