I am using Vegas Movie Studio Platinum 9, and sometimes, while previewing a video I've made, the video would have "blackouts," that is, it would just go blank for about a second, and then go right back to playing normal. It keeps occurring in the exact same spots in the video too, and is very annoying.

I thought maybe it had something to do with it just happening while previewing the video, but I tried saving the video and rendering it to view it outside of the Vegas program, and in the exact same spots it would blackout for a second.

Anyone know what is causing this/how to fix it? It is very annoying and troublesome. I would like to finish editing the video I'm working on, but this is hindering my progress...
