I made a DVD from a concert on TV with 5.1 surround. I didn't save the source files and am now trying to bring one of the VOB files back into Vegas Pro 10.0d. The audio comes in as stereo. I could live with that if all the surround channels were blended in, but the center channel, and therefore most of the vocals, are missing. I set the audio project properties master bus to 5.1 surround. I don't know what else to try.
