MultiAVCHD Fails to encode AC3 audio

So I am working on putting a fanedit on an AVCHD. I exported the sound out of Vegas as a .w64 to avoid using Vegas as an encoder. I then used eac3to to convert the .w64 to AC3, using the default settings. I then add my avi file without sound to multiAVCHD, enter the file properties, and add the AC3 audio track. Finally, I choose my transcoding settings for the video. The video transcodes just fine but I get an error message when it gets to the audio and it skips the audio track. I then end up with an AVCHD file structure with no sound. The log output is below.

I was under the impression that AC3 was compatible with AVCHD so I do not understand what the problem is. I would greatly appreciate it if someone could point me in the right direction. I have tried multiavchd 3.0 and 4.1 to no avail. I also tried 640 and 480 kbps, no luck there either.

Code:

P.S. Hoping this is the right forum, it could go under authoring but I felt like its mainly a file conversion issue.

Sounds like it is missing a codec to decode AC3, but doubtful that is your problem since it shouldn't be trying to transcode it anyway. All you really need to do mux the AC3 file you already made. MultiAVCHD has a re-muxing (re-authoring) mode where you can add and delete tracks from an already exist BD or AVCHD structure. If you go this route and just add the audio track to the video within the AVCHD you just made, you should be golden.

Or you can use a different program like TS-muxer to mux the video and audio together into an M2TS file, which you can then dump into an authoring program.

I don't know anything about .w64, but I would just export out of Vegas as ac3. I don't remember anyone having problems doing that with Vegas.

^ THIS. While the video encoder is still crap, there is really nothing wrong with the audio encoding from Vegas. Just export AC3 and avoid headaches.
