For the past few months I've had issues with the center channel randomly dropping out in the middle of a blu-ray movie on a Yamaha RX-V663 receiver. For everything else, it works fine: playing video games, streaming Netflix, and watching TV. After reading this thread, I decided to check my settings, and sure enough I was set to bitstream. I switched to PCM and had a nice glitch-free viewing of Snow White and the Huntsman last night. I had to turn up the receiver 3 clicks, but no biggie.
