I am working on a blu-ray disc in DVD Architect and want to do 5.1 surround. I edited an mpeg2 file in sony vegas and a seperate ac3 file for my 5.1. When I import it into dvd architect, it plays fine in the preview but when I go to author the actual disc, it says my ac3 stream needs recompressed and is not compliant with the disc. I've tried changing audio formats but I get this error each time and when it does recompress, the disc never plays audio. I looked all over for a solution but I can't find one. I even tried going back to DVDA 5.2 but I still have the exact same problem.
