[MPlayer-users] dts in libavcodec not working

[khayos]

Hello all,

I've been fighting off and on with libdts for awhile now, and have put
in some concentrated time on it for the last four hours or so because
I have a DVD rental (Sin City) which requires it.

What I've done most recently is:
1) cleaned my system of all mplayer and codec files, and all dts files
2) installed all mplayer codecs: essential and win32
3) ./configure && make && make install for libdts (aka libdca, from
videolan), no errors -- yields /usr/local/lib/libdts.a primarily
4) mplayer: ./configure --enable-libdts --enable-win32 && make && make
install, no errors
5) ensured that all appropriate lib locations show up in
/etc/ld.so.conf, and got no errors with ldconfig
6) ensured that mplayer itself is still working properly by playing
other titles on this DVD (which don't use dts) -- all systems go

But when I go to play the main title on this DVD, I get the same
message I've been getting for the last however many weeks, any time I
need something dts-related; the mplayer output is listed below.

In the reading I've done, I've most often encountered people saying
that the hwdts codec gives them poor quality sound, but I get nothing
at all.

Just to make sure dts shows up, I did a check on the mplayer audio codecs:
[20:47:47][hyperion] ~$ mplayer -ac help | grep dts
ffdts       ffmpeg    working   DTS  [dts]
hwdts       hwac3     working   DTS through S/PDIF
[20:47:51][hyperion] ~$

For curiosity's sake, my soundcard is:
02:06.1 Input device controller: Creative Labs SB Live! Game Port (rev 0a)


I've done repeated searches for keywords related to this topic and
while I found a fair number of mplayer and linuxquestions forum posts,
none of the suggestions that I found had any positive effect.

If anyone has any information that might help me in this matter, I
would be most appreciative!  If the guru help people out there need
any more details about my setup, just reply to this and I'll answer it
as immediately as possible.

Thanks in advance.
