I do work for a school that was given a Phillips DVD recorder. They have a very nice camera that output only S-Video into the Recorder with a wireless receiver for the Audio so all things said the quality of the DVD is not to bad. They want me to trim the beginning and end, then combine the 2 (~1 hour lectures) on to one DVD. The Phillips is a .VOB extension so I renamed it to .MPG and loaded into Vegas but there no audio track. Any ideas?
