I am not sure what audio format I am listening to when I play a video from my library .

I am using a WDTV Live media player connected to my Onkyo Receiver (AC3 and EAC3 capable) when playing movies stored in my networked computers.

Whenever I have a movie with EAC3 , I get no sound when using network shares but no issue with AC3 audio. So I usually transcode the movie to AC3 audio before playing it.

However when I select the same movie using media servers instead network shares, I do get sound and video. My question is whether I am listening to EAC3 or AC3 transcoded by the media server?

Thanks

BTW All computers are on latest version of WIndows 10
