Hey folks.
I’m sorry if this seems a silly question.
I get the topic as a message when I start up a animé episode that I want to view.
Underneath is an information box that says:
This file contains an audio track in an unknown format. You may need to install a DirectShow decoder for this format in order to hear the soundtrack of this file
How do I figure out what what format the file is in? 
gspot

if it reports the needed audio codec is tag 2000 (8192), then you’ll need the AC3 filter.
yeah me 2 its for the Eureka seven 1 huh
Yha so I had same problem and used Gspot and it said the codex was
0x706d (FAAD AAC)
Well That cant be found lol
Why dont you try this player? www.mpcstar.com I also had this same problem with one of my DTB episodes , which was in mkv format. The audio format was not supported either.
However this mpcstar player could play the vid.
audio format is not supporting in divx player what to do?
i had a solution download total video player here : http://download.cnet.com/Total-Video-Player/3000-2139_4-10552696.html

Just download this filter
