Hi, we are prepping some BetaSP footage for a DVD and I am getting some moving green lines at the top of some of the footage; not sure if it’s the deck tension or a bad tape; any suggestions for removing the interference in Vegas?  Some of the footage is B&W so I applied the B&W filter over it but other parts are color.  "Zooming in" the track is not an option.  Thanks in advance for any advice.
