oh wait before you guys get all proper on me, It does support it but the drivers arent ready yet. What you fail to realize is that dts to analog was only 2 channels. With the previous cards like the xmeridian, you can play games, mp3s, and movies all in 5.1 dts and dolby digital live, the audigy did not do this, nor did the xfi.
What you have to realize is that this is a huge step forward for the audio card industry. Everyone has been wanting creative to license out their eax 5 to other companies and finally it happens. You have a card now that can play eax5, encode dts, encode dolby digital live (waiting for the drivers to incorporate it), and upgradeable opamps. I have an Razer Barracuda AC-1, my card can encode in dts 5.1 by transcoding eax 2, that is awesome. Now it supports eax 5, can you imagine how happy gamers will be when they find out that encoding dts 5.1 and eax 5 coexist all one card. On top of that this card has excellent sound quality, and the ability to just play everything in 5.1 dts through a receiver on ONE cable, is sooo incredibly convenient. For guys like me that have a yamaha receiver, furman power conditioner, 32" lcd tv, 5.1 sound system, and rotel amp. Home theater enthusiasts like me are sure to love this card. My friend has one of these cards and i love it. These drivers that come with the card are bare bones compared to the ones that come with creative xfi. If you bother reading user reviews or forums from other websites you'd always notice users mentioning the same thing over and over: EAX 5 with encoding dts, striped down drivers with no bloatware, stable drivers, etc... Now you have it. To me this card is future proof, what else do you need? Except for the drivers that allow encoding of DTS.
