When I called the dealer they told me none of the TV would play through the surround sound SURE THEY KNOW WHAT THER TALKING ABOUT hope this helps.
A couple weeks ago, I pulled the head and found the TV hookup was reversed (in / out). Swapped them and all was good. I don't think the people doing the wiring are familiar with technology.
