first of all, sorry for my english, i'm spanish…
I have installed Mediatomb in my server (Ububntu Server 12.04) and after config it, all works fine, but today i've tried to play a film with 3 audio tracks, two of then are ac3, and they work fine, but the other one (the spanish track xD) are in AAC and my samsung tv, where i normally use Mediatomb, alerts that this track is an unsoportted audio format, what can i do¿?
Thank you!
