i've uploaded a sample to incoming, "dtsac3audiosample.avi"
i'm not 100% positive if this sample contains sound
it could be a silent intro clip.

Some dvds have dts audio instead of ac3 audio.

the user with the sample file said a52 didnt decode it.

i think VLC might have DTS AC3 working with this package
http://www.videolan.org/dtsdec.html
which was based off a52

tried some windows codecs, all fail.
