i think the reason why DTS MA-HD is working with Splash Pro is that it has a DTS Core...i bet Splash doesn't even support the native DTS MA....
now i know why there is no audio when i played Dolby TrueHD movies....it doesn't have a Core audio like DTS MA-HD...
i tried even installing LAV filters but no audio i guess Mirillis do not support third party decoder...but using VLC TrueHD played flawlessly....come on Mirillis, we know you can do it.
