It's a Vizio TV and a Onkyo remote.  I can't turn off CEC because I rely on
ARC for the smart tv functions in my Vizio.  I will consider using an
optical cable (and believe I had done so in the past) and maybe just plug
all the devices into the TV and have the harmony change inputs on the TV
instead of on the Onkyo.

I will also follow Gary's advice and see if there is some setting in the
Onkyo that needs to be changed.

I don't think I will spend $50 for an adapter.  Pretty annoying Nvidia
doesn't include that functionality.  I can't imagine it would cost more
than pennies to add it per card.
