As a father I enjoy filming my family with a ‘customers camera’ that export files to MPG in AC3 format.
But as a possessor of Adobe Premiere Pro I would have been happy to work my movies. Unfortunately, Premiere Pro will not read the sound of any AC3 encoded files (certainly due to some licensing reasons).
Fortunately there is a work around I found on Adobeforum, just copy the file ad2ac3dec.dll from Adobe Encore Folder and past it in the Adobe Premiere Pro folder. Relaunch your application and your file will have the sound included!
