Yup just tested this and, as you guys found out, we are getting 5.1 sound. Unless we can find evidence to suggest otherwise, I suspect we are getting 2ch TrueHD downmix for L/R and the other channels are the core DD stream. Lipsync on Matrix was also good via this route.

I now need to do some extended listening to see if it's worth going down this downsampled TrueHD route, rather than running with the default DD+ stream.
