I have encoded about 250 DVD's into hard drive files (vob files, I think) and can not figure out how to get the multi-channel audio to work. ON WMC 2005, I have 5.1 surround on these files output to my pre/pro via SPDIF, but in MediaPortal I can not get 5.1/DTS/etc sound. What am I missing? I have poked around through the settings but can't seem to find it. I have an cyberlink DVD 7 Ultra installed which also plays these files with surround sound.
