Problems with Sony STR-DH550
I'm having trouble with setting up this receiver. My setup is as follows: Samsung bluray, Roku stick & Tivo OTA all hooked to receiver via HDMI. Then HDMI from receiver to Panasonic TC-P50X1. When receiver's HDMI audio is set to "amp+tv", the audio & picture work for all components. However, I only get PCM 2.0 48 khz. If it switch receiver's HDMI audio to "amp", the picture drops out for the Tivo & Roku, but not the Samsung bluray. Also, when doing this, the Samsung works correctly (can get DD, DTSMA, etc). TV's Viera link doesn't seem to affeCT audio formats. Tried swapping cables & resetting TV & receiver. Please help.
