Sound like that guy trying very hard to update ya to EA stuff. I am currently running 10.2.5. 1 HC800 and 2 HC250. I use ROKU for my 4K to TVs. And have a Pioneer 4K receiver for Surround sound. I have the HC audio output going to my 4 rooms thru a Niles 12 channel amp. Sent from my iPhone using Tapatalk
