Thanks for your fast reply. I've just bought a 2nd card and don't know about the difference between Model number (SB0460) and Serial Number...
I unlocked DTS Decoder (Decoder tab appear in Creative Audio Control Panel) successfully in WinXP 32bit. But I stucked with Windows 7 64bit.
PCI X-FI ExtremeMusic, Model SB0460, SN: MASB0467xxxxx
