I have a Sherwood 6108 receiver, and cannot figure out when DPLII is being used. I can get DD, and DTS signals from my DVD player just fine, and one a few digital cable channels. On other channels, it shows up on the reciever as both Digital, and Pro-logic. When it is in DD or DTS mode.it shows you that you are in that mode. Am I in DPLII when both lights are on? Also, if i am in the mode when both lights are on, if I switch to "stereo" the digital light will come on. Any ideas? Thanks.
