Here is a patch to add multichannel support to the native DTS decoder.
It also utilizes the downmixing coeffients, which is not done currently.
 The default coefficients are based on the comments at the bottom of

downmix 5.1 to stereo:
ffmpeg -f dts -i stream.dts -acodec pcm_s16le -ac 2 stream-stereo.wav

copy 5.1 direct to wav:
ffmpeg -f dts -i stream.dts -acodec pcm_s16le -ac 6 stream-5p1.wav

Note that channel reordering is not done yet, so the multichannel output
would be in MPEG-2/4 channel order (C,L,R,LS,RS,LFE).
