Hi,
I found the Virtual surround mode very interresting.
A Nice feature would it be to make a surround mode using a 4 or 6 channel speaker system.
A real Dolby surround software decode might be to expensive in liecense, I am thinking about something similar to the "Watch TV Mode" Effect Filter in older SB live! drivers for windows 98 (don't know about now, i don't have a creative vard anymore).
