I'm trying to rework some ac3 xvid files using the guide that is listed on this site. All goes well until the last step, when I attempt the simple multiplex in tmpgenc using the mp2 file created by Bewsweet and the audio stripped mpeg file created by tmpgenc earlier. When I attempt to load the audio file, it says "Illegal mpeg audiostream". Anyone have any idea on this. Thanks in advance. Also, if anyone has a simpler suggestion for encoding ac3 files, I would love to hear it.
