[QUOTE="jameson_uk, post: 700783, member: 11220"] SPDIF will only carry stereo or DD/DTS so TrueHD gets a little messy DTS-HD is nice and simple in that it is always contains a DTS core so if you play a disc with a DTS-HD it will just output the DTS core. TrueHD however does not necessarily have a DD core track (what should happen is that the TrueHD and DD shoudl be separate tracks) What does happen however in some audio tracks is that a DD track has been interlaced into the TrueHD track (so you actually have two tracks which appear as one). The theory here is that if your player does not know what to do with the TrueHD track it will only see the standard DD track and ignore the other bit) So to answer your question, it depends on what type of TrueHD the disc has. If it has this interlaced DD track then I think this should work as normal. If it only contains a TrueHD track (which will have to have been an rip with some stuff removed as it must have one of the mandatory codecs) then you need to do something to decode the output and then re-encode to DD Using a recent FFDShow tryout you will need to set the options to decode TrueHD and then set the options to encode audio to DD [/QUOTE]
