Right now I'm looking for samples with joint channels coding as well as
sum-difference channels coding. I suspect joint channels coding might not
be common though because DTS is usualy targetted at high bitrate / high
quality applications.
I'd also like to have a few samples using high frequencies vector
quantization. I already have a couple of these, but more would be nice.
Basically if you see libdts output a debug message on a stream, that should
mean that I'd be interested in having a look at this stream ;)

DTS over S/PDIF has been available in VLC for some time too ;)

Shouldn't be difficult as the api is almost identical to the liba52 one.
Have a look at doc/libdts.txt. But bear in mind that some things are not
implemented yet (Dynamic Range for instance).
