I have a hollywood Plus running on an XP system with release 2.3 beta drivers. I have a Creative Labs Soundblaster Live 5.1 card plugged into Mercury HT 4500U 5.1 speaker system. When I play an mp3 or any other sound in XP all 5 speakers work OK and all the diagnostics check out fine. When I play a DVD on my H+ and have the audio set to Analogue Surround the sound comes out OK (of centre front left and right). However when I select either of the 2 other audio options, Digital - DTS or AC-3 I get no sound at all. I know my speakers are DTS and AC-3 compliant so why no sound ? I assume it is an H+ issue cos all other software works OK.

Thanks in advance
