Is it to do with how the content is broadcasted or am I doing something wrong?
My views (except when I am looking out their windows) are not those of my employer.
cyril7: The spdif port either optical or electrical (coax/rca) carry the identical traffic, the HDMI will only carry 2ch on a HDi.
So is it getting the PCM 2ch feed when you select a channel thats not HD (ie with a DD attached feed). Another potential problem is that the DD stream is only 2ch and the AVR decoder is doing something odd, does AVR show that its detecting a DD stream?
