I'm using Voukoder to export 5.1 videos in VEGAS Pro 20, and every dolby option seems to work fine except the Dolby TrueHD one.
When I try to render a project in Dolby TrueHD, the render bar goes to 100% in an instant, but the video is nowhere to be found. Also, you can't choose to open the video itself or the folder.
The same happens when you try to only export the audio in Dolby TrueHD.
