Running Server 19 and Vegas Pro 17. Upon trying to render a video with 6 channel PCM audio to Dolby AC3, nothing happens. After making proper selections and clicking RENDER, the current dialog disappears, and nothing else happens. All parameters, options, and files are valid. The exact same files and setup renders just fine on my laptop, albeit much slower. The Server 19 machine is relatively new but I'm pretty sure it worked when Vegas first installed. Sorta remember it downloading codec.
