thanks for the help.. but.... i'm sorry it doesn't work for me also if i change the from mov to mkv or mp4
if i use only the mpa codec i don't get the dolby sound. Instead if in configuration of mediaportal i postprocess the audio with ac3 filter i get the dolby digital sound.... i don't know why
Did you go in MediaPortal Config and set MPA to use SPDIF, I think it's under DirectShow filters in Expert mode.
