My friend just purchased a new dvd-a/sacd player all in one. It is the pioneer DV-578a plugged with analogues into the dvd 6 ch input of a kenwood VR-615. All seems correct. But, when i play a dvd-a or sacd, the reciever still keeps the pro logic light on. Also, playing dolby digital dvd's result in a lack of surround speakers playing at all. The reciever also has a dvd optical and its own analogue section so i am assuming the dvd 6 ch is a external decoder type of deally. If not, well, then there's the problem. Unfortunately, my friend does not have the manual for the reciever. Does anyone (Wilkes) know why it is doing this?
