We got digital cable about two weeks ago. I just ordered a pay per view movie through on demand and the question I have is my recieever did not seem to switch to either dolby digital or DTS. In the creditd it says the movie was in both. I have the cable box hooked up to my Kenwwod VR 507 recevier using the digiatl coax connection. I made sure that the reciver was set to digital auto sound. I tried digital manual sound but I still could not choose Dolby digital. The reciever never changed from pro logic.
