Everything I do with VideoFactory 2.0 is great, until it is time to view my rendered product. I render to digital video, and the video is fine, but every 15 seconds I receive a sound glitch - I get about a 1/2 second of silence - like a hiccup - and then the sound continues until 15 seconds later - the hiccup comes again. Has anyone encountered this? How do I fix this? HELP!!!
