i dont see bitstreaming capabilities for the 300. so i would say no, only pcm audio from blu rays. someone correct me if im wrong

edit: or did i hear about a insider saying it was able to decode true hd?

edit edit: i did a search and did find an insider saying there was decoding of true hd. i dont have your player so im unsure on how to enable it. but i think you need the latest firmware update. and you would have to use the analog out on the player.
