NHL 2002 and SSX Tricky are the only two games available on PS2 which supports realtime DTS and not Dolby Digital. The only console on market today with realtime Dolby Digital is XBOX because it has built-in Dolby encoder. There are more games for PS2 coming in DTS 5.1 from EA. The only thing that PS2 can do DD5.1 is in cutscenes like eg. The Bouncer and MGS2, it sounds just AWESOME!!! There are games like Soul Reaver2 and ExtremeG3 which supports Dolby Surround, at least if developers use that technique it\'s damn good becuse Dolby format has very tight bass compare to DTS. Sure DTS sounds very clear but it lacks some bass because of weak LFE channel compare to tight and heart shaking bass that DD offers. I hope all future titles supports DTS in PS2 or DD5.1 in cutscenes and Dolby Surround in realtime. It would be cool if Sony or Dolby releases some kind of upgrade which would support realtime DD5.1, even if that thing cost $100 i\'ll just get it. Sound is soul of movies and it gives feeling to game, imagine playing an FPS game with 5.1 support you could hear if someone is at your back or at your blind spot, you could not see but you can hear and thats like using your sense, "the sense of hearing" that would be so coool.
