Hi. I want to combine 3 separate veg files into a master and burn this to a DVD. I find that if I nest them on a timeline then render them (mpeg2) I get some graphic vibration (titles, photo of a women in a polka dot dress, etc). This vibration does not occur when I render them from their respective veg files And I found that I can't copy and paste the timelines into a master because audio envelopes disappear in the process. Any suggestions? I' m using Vegas 7.0d
