Last night I switched to a Showtime channel and the comedians voice sounded like a robot. It was all garbled and sounded funny. I turned to a different channel and it was fine and then back and it was still messed up. I recall the other night watching Gold Rush where I thought the voices sounded a little funny. My 8 yr old told me this morning that his shows, the people were talking funny. Any ideas? I have the HR34. I'm using the digital RCA out to a Denon 4800 receiver. I have had this Denon for 10 years and never experienced this before with TW boxes hooked up both optical and RCA.
