[MPlayer-users] Dolby digital .avi file : identification output please

Hi there,

I am somewhat confused here trying to rip [I own the DVDs, Like LOTR
trilogy] the DVDs while retaining Dolby digital tracks.

If any of you have an avi file with proper dolby digital / DTS sound
track retained which you play using SPDIF for your digital amp using
coaxial or fiber optical cable [TOSlink], then can I have the output of
"file movie.avi" from your computer?

I am confused between whether to use hwdts, hwac3 while encoding
[acidrip + cache dvd] and the best I get is the following -

RIFF (little-endian) data, AVI, 640 x 256, 23.98 fps, video: XviD,
audio: Dolby AC3 (stereo, 48000 Hz)

But I think I should expect to see something like 6 channel instead of
stereo. But then I am not sure how hardware decoding of DTS/DD takes
place within my amp [all SPDIF cables are stereo, so it may be stored
inside as encapsulated and may have been meant to be decoded by my amp].

If someone has an authoritative answer to what does Linux returns on
seeing a 6 channel dolby digital track within an avi file, I would have
something to compare my results against.

Many thanks,
