We have a Yamaha HTR-6130 AV receiver. When we first bought it, we had a regular TV, no digital, but when we played a DVD, it showed all 5 speakers being "used" on the receiver. Recently we bought a new digital TV and we also now have satelite with HD, but no matter what we play the receiver will only show 2 speakers being used. I even tried a DVD I KNOW played with 5 speakers before and it's also only showing 2 speakers used. This may be a repetative question, but we are so frustrated at why we used to have it and now we do not, any suggestions?
