Ok, to start with I have a Montego DDL soundcard with optical cable, and a Logitech z5500 speaker system that has dts hardware decoding, and I am running Windows Vista. Whenever listening to music or doing anything with audio the screen on the logitech thing says "Pro logic II". When I try to play a dvd in dts in media center, it won't let me select dts in the dvd menu, and once again I'm stuck with pro logic II. I have DDL 5.1 encoding set on the soundcard, because it doesnt want to stay on s/pdif 48khz when I try to set it to it. Please someone tell me where I am going wrong, I have searched many forums and it is only making me more confused. Thanks
Your player MUST support DTS playback. I'm not familiar with Vista, and the Media Center, but I doubt that support for DD and DTS came as a standard feature. I never found a free one...... I ended up getting WinDVD. You can download the free trial here, to see if it works for you: http://www.intervideo.com/WinDVD/ Good luck!
