Hi,
I have the same problem :
when I check "SPDIF" option in BSplayer, it has no effect.
I use for years a 2001 version of WinDVD (2.3) with the "SPDIF" option checked and it work fines : DolbyDigital and DTS data pass through the digital optical output of my soundcard to reach my external DD/DTS decoder&lifier.
So why can't BSplayer do something so simple :?:
Thanks for your help :)
