Yep, all fine as DOLBY/DTS is passed through to my receiver when using XBMC. MPCHC
works OK as well, just not WMC
It's just WMC 7 that doesn't work correctly.
Strangely, when doing a SPEAKER SET UP TEST, my receiver shows DOLBY D, so I am now assumnig I am missing some software, such as FFDSHOW ??
If I could get WMC working as I want it, I can then start investigating YAMMM or MEDIABROWSER.
