I have the SurCode plug in for Premiere and the stand-alone Compressor 4, and both will generate 5.1 AC-3 files that load perfectly into Encore and produce a 5.1 DVD or BD that decodes fine. I made a 5.1 AC-3 file using Audacity and FFmpeg which plays back via VLC correctly. However, when I try to import into Encore as an assest, I get this message:
Could not import file [filename.ac3]
More than two audio channels for this type of encoding is not supported.
Am I missing something? Is this a licensing issue? Reading older posts, it seems that Audacity-generated AC-3 files did once work. See here: http://forums.adobe.com/thread/511930
Thank you for any help or suggestions.
