Hal, I use Womble MPEG Video Wizard, which is a slightly more robust program. I'm not sure if the export tool is the same as the MPEG-VCR, but if it is, the export window has four tabs, for [General] [Video] [Audio] [Monitor]. On the General tab, you can either "separate" the one designated output file into two files (a video file and an audio file) or they can be "multiplexed" into one file, where those two quoted terms actually toggle the function back and forth on the interface.
