So I am opening up my Encore project to see why a very well authored DVD which has audio on a DVD Player is not providing the audio stream on a PC.
One thing I noticed on exploring the file structure of the DVD is that the main and only file directory is TS Video.
Encore settings that are relevant are: under adnvanced on the Project settings Transcoding Audio is Mpeg-1 Layer II
One video was rendered from Premier with Dolby audio and did not get transcoded,the other I used PCM and it required transcoding...wierd huh.
Could this be a problem further back in my workflow IE rendered MPEG 2 from Premier
