BIslander is right in their post. My home theater system is not ARC capable. There is also no Digital Audio input for the unit. It amazes me that Sony would manufacture some equipment that is not compatible with other Sony equipment. I've been a LONG time Sony fan, but to spend as much on this as I have, I expected it to be compatible. The quality is traditional Sony, but with this issue I'm disappointed. Looks like I'm either going to have to upgrade my home theater system or spend ANOTHER $100 for additional equipment just to make this combo work.
BI, thanks for the info. You were right on!
