I have a Video .vob file (from DVD) that will import the video portion fine into Movie Edit Pro (latest version), but it will not import the sound file. I notice it is not building the frametable for mpeg.
I have tried differen files same result.
Make sure to activate the Dolby Digital Stereo decoder in the program. This is necessary to decode Dolby Digital audio properly. You can find the option under the "Help" menu => "Activate additional functions" in Movie Edit Pro 14.
