Aside from 5-channel/7-channel stereo mode and the real digital decoding formats that have been so hotly debated (DD, DTS, DPL2, DD EX, DTS ES, and Cirrus Extra Surround for some proprietary 6.1/7.1 stuff), I haven't heard anything about any other DSP stuff. Maybe we'll know more when the manual appears online one of these days.
