For those using 5.1/DTS encoder units such as the Panasonic CY-AC300EX, you should check this out. http://www.platinum-records.com/detail.aspx?ID=6944. Let me know if know of anything compatible. It appears to be the best one I have came across so far. Powered by the 5v on the USB/stereo mic/ toslink out/analog out. Pretty good
