Hi Shannon01, Thanks for the fast reply
The set-top box set up system you gave me, was already tried with no luck.
What I don't understand is why am I only getting control to turn the TV on with no volume control, and no control to turn the TV off. The only thing I haven't try is to upgrade the HDMI cable to a better cable that is mark HDMI (ARC).
Is the Directv RC72 remote control RF? and if so can I switch to IR to see if I get volume control?
If I do switch over to IR, can I still do program channels?
