I now use ASUS Xonar HDAV 1.3 Deluxe. Now everything goes well with this great sound card. However, I can’t still tell the difference between Dolby and DTS.
 
I try to find the difference between this two “format” (or “technology”???), but it’s really abstract for me. Does anyone can give me any idea about the difference….And why soem model of Xonar have both Dolby and DTS while others just have Dolby?? Really thanks for kind info.

Dolby/others makes a wide range of 'codecs' and 'DSPs' or digital signal processors.  Dolby Headphone is a surround sound emulation DSP, where as DTS is a codec for surround sound information.
 
If you'd like me to go more into depth, let me know.

DTS isn't a Dolby codec.
 
Dolby and DTS are two competing routines....

Ha!  I mistook DD for DTS.  Good call.  Corrected.

Lossy DD uses bitrates up to 640 kbps. Lossy DTS bitrates are 768 and 1500. Lossless Dolby TrueHD and DTS HD-MA should sound the same.
