[FFmpeg-user] CD-DTS

Hi list,

Has anyone succeeded in making a CD-DTS (a.k.a. DTS Audio CD a.k.a. 5.1 Music Disc) ?
I'm desperately trying to find the right combination of options to create a valid, burnable wave file that spits DTS on my receiver.
Unfortunately, all I get is white noise.

The key seems to pack a DTS flow inside a classic 2-channel, 44100Hz, PCM-declared WAV container.

$ ./ffmpeg -i input.aac -acodec dts -strict -2 -ar 44100 dts-output.wav
creates a 6-channel wav container for the DTS datas and
$ ./ffmpeg -i input.aac -acodec dts -strict -2 -ar 44100 -ac 2 dts-2c-output.wav
downmix the 5.1 aac input to a 2-channel wav file

I tried to bit-bang the dts-output.wav so the wav container is declared as wanted but it fails.
The file at http://www.lamoateffe.com/samples/RedHouseDTS.wav is a valid wav-packed DTS file.

Any advice welcomed.
