If I play a DVD in WinDVD I get full glorious DD surround passed via s/pdif to my amp. It shows a DD input and it sounds great. If I play the same DVD in MCE using the WinDVD decoder I don't get the same, I get sound to my amp but no DD signal. My soundcard is a Mystique. Initially I set it to just output 2 channel sound via s/pdif. WinDVD's settings work and it still correctly sends full DD to my amp. MCE is still the same, no DD signal. If I change the mystique to 5.1 Dolby Live processing then WinDVD continues to work correctly and this time in MCE I get a DD signal but it sounds nothing like the true DD coming from WinDVD. Any ideas what's going on?
