Apparently it requires setting the rate to 4x the actual.

All other than DTS-HD :
ffmpeg -i inputfile -f spdif -acodec copy output.spdif
For DTS-HD (e.g.), to get more than the core you need:
ffmpeg -i inputfile -f spdif -dtshd_rate 768000 -acodec copy output.spdif
(768000 makes output suitable to be played back as 8 channel 192kHz)
I'm using ffmpeg svn from 20110311 it doesn't like the dtshd_rate option. They must've changed something.
