Solved Alternate audio track not rendering out of DVDA

Hello all, 

I am producing a BluRay disk for a feature film. Everything has gone smoothly, menu creation, media renders and so on. I've burned a couple test disks and everything works except....

I want to have an alternate track for a Director's Commentary. I have everything in there and encoded. I have a supplements menu where the track can be selected. When I preview the disk in DVDA I select the track from this menu and it works. I select the track from the remote and it works. However, when I render out and burn the movie it is not there. When I go into the ISO file and streams the alternate audio track is not even rendering. For the life of me I can't figure this out. According to the manual this seems to be possible. And the fact that it works within DVDA puzzles me even more. 

My track has been encoded using Adobe Media Encoder and I've ran it through the same BluRay present for MPEG2 as I did the film. I've tried encoding an AC3 of it but DVDA won't read that. 

Am I missing something?

Thank you for your help. 

I don't know the answer but try encoding the track as a wav file and ask DVDA to recompress it to AC3.

For whatever reason that worked. Thank you so much.
