Has anyone else had a problem with black frames magically appearing in their rendered video? In particular, when you are using MPEG2 files as source media? I have a questionable capture device, and I suspect it may be causing the issue, but it also possible that VV3 isn't handling MPEGs very well as source media. I have a work-around that seems to solve the problem (rendering the MPEGs as AVIs before adding to media pool). I think there was a thread in this forum some time ago about a similar problem.
Thanks,
Don
