had a Samsung DVD player connected via HDMI to my Yamaha 4600 and never had a problem with decoding etc..it has recently stopped playing DVD's (plays audio CD's fine...) so I bought a Pioneer Elite DVD player, and connected to the same HDMI cable...now my question is that no matter what settings I chose on the disc 5.1DTS, Dolby 5.1 etc.., my Receiver interprets the input as "PCM", were as before it would appropriately select which format was being sent ("digital", "DTS") etc.....is this normal?
