Hi dogman, thanks for the reply.
in the time between my post and your reply it started to work!
So somthing is getting through the optical spdif. Not what i was hoping for but somthings there.
I think this card outputs virtual dts and i was hoping it would pass through the original encoded DD and dts 5/7.1 from the disks being played so im either missing a set up somewhere, an internal interconnect, or its not what i thought it was. Do you know if these cards or another you could recommend will handle a DVD's orginal encoded DD or DTS bitsream and also handle 'DTS HD master audio' and 'DD TRUE HD' from Blu Ray?
Im running Power DVD 9 that came with the Samsung Blu ray. I did upgrade to PowerDVD 10 Ultra 3D but that was over £50 and just crashes the computer everytime i try to play a Blu Ray
