Last week I bought TMPGEnc Video Mastering Works 5.
I couldn't convert to AVI with AC3 Audio. I already contacted TMPGEnc support. They told me to search in google for a directshow compatible ac3 codec. OK, so I found AC3 ACM Codec to work with Video Mastering Works 5.
But it doesn't encode to AC3 5.1, only 2.0 and 1.0 works.

This was the only AC3 codec that was working with this program. TMPGEnc Support told me to switch to another format like .mpeg for AC3 5.1. This program is really not cheap and it doesn't support AC3 5.1 output in avi???
Even free tools like XMediaRecode and MediaCoder are working better in avi output.

Is there any chance to get it working with this programm?
