mplayer -demuxer lavf -lavfdopts format=dts file
works for me. I will see what can be done to that DTS-in-WAV
detection patch.

On my PPC with some samples from MPHQ
(ffmpeg -benchmark -f dts -i file -f wav -acodec pcm_s16le -y /dev/null):
03_NEUE_MUSIC_BERND_THEWES1_kleine...
with libdts: ~22 sec
with dca: ~7 sec
06_NEW_JAZZ_SSQ3_ENERGY_DTS.wav
with libdts: ~20 sec
with dca: ~7 sec
Fire__VooDoo_Studio_1_min.wav
with libdts: ~14 sec
with dca: ~5 sec
I suppose on x86 native dca will be also a bit faster than libdts.
