I've just added a blu ray DVD ROM to my pc and have started to move my small blu ray collection to my hard drive. I'm using DVDfab and rip the files as ISO. Playback has'nt been a problem as my pc sends the audio through a sound card to my 5.1 surround. However I've just bought a LaCie LaCinema HD to watch my films in different room. The picture quality is great but no sound on channel 1 (digital)! Flicking through the other sound channels works fine, e.g different language or audio commentry, but the main channel 1 refuses to play audio. I suspect its the way the film was ripped but I cannot seem to find any other options to change the audio set up.

Thanks
