Just upgrade to Bluecurve and all seems fine, except I get a XRE-03090 on just the 4K channels ( SN and TSN ).

I have 2 TVs , one is 4K and one is not.  On the TV that isn't 4K I get a message saying my display is not 4K, so that makes sense. But on the TV ( LG C9 ) that is 4K I get the error. And on the same 4K TV I can watch 4K videos thru the SHAW Youtube app no problem.

Talked to SHAW and they had me connect the Xi6 HDMI out directly to the TV ( was going thru a Yamaha receiver that passes every video source known to man ) and I still get the error. 

XB7 in bridge mode, Xi6 using ethernet 5e cat cable,  18GB HDMI cable to receiver then same to LG C9.

Ideas?
