When you attempt to import XDCAM EX clips or MP4 files into Adobe Premiere Pro CS3, you receive the error message "Unsupported format or damaged file."

2 working solutions are 1. Download the ad2ac3dec.dll (AC3 Stream Decoder) by MainConcept AG and place it in the main Premiere Folder. 2. or change the .MP4 extention to .MOV
