So here is the situation:
I have a Marantz SR 8500, OPPO BDP 83 going into the 7.1 inputs, and the Panasonic Plasma V10 series.
Somehow I never had this problem before but now when watching blu rays the audio is behind the video. This means I can't use the delay functions on the OPPO as it would only further increase this problem.
Speaker settings seem set correctly for the distances so I am a bit baffled how to get around this?
