AC3, DTS & Pro logic downmixed to Stereo

So those without surround speakers can hear everything Maybe MPC can do most of this & output to PCM stereo

Downmix to AC3/5.1, 4.1/Pro Logic, Stereo or Mono depending on audio setting selected in Xbox dasboard.

Some open source project with DTS code: (Maybe code could be used to add DTS?)

Hypercube Transcoder Open Source DTS filter http://hypercube.is.dreaming.org/ (inc. RAW PCM output support) Only support DTS 5.1 yet but plans for 7.1

"BeSure" has VOB/AC3 to CD audio (inc DTS) conversion. http://dspguru.doom9.net/

Hi,

This patch add software dts decoding using libdts ( http://www.videolan.org/dtsdec.html ). It require the very latest libavcodec (FFmpeg) CVS. I've only tested it with dts track of a vob file.
