Movie Playing With Rainbow of Colors Scrolling Across Screen

[DennyHayes]

Every avi file I play with different versions of VLC all of a sudden play the movie with a rainbow of colors scrolling across the screen, and a miniature picture in picture of the movie randomly roaming around the screen. The miniature picture in picture of the movie doesn't seem to have the rainbow of colors rolling across the screen. I don't know if this is a virus in the computer, or bad VLC aps, or some setting in a VLC file that went haywire. Has anyone here had a similar experience?
