I have connected my LG 65 OLED TV to an Onkyo AV receiver using HDMI ARC port. I have xfinity set top box connected to the receiver through HDMI input port. I would like to control TV and set top box using the LG magic remote. Most control works but I am not able to see channel guide or channel list using the LG remote. It seems the only way for me to use the channel guide is to connect the xfinity box directly to the TV and not through my receiver (another cable through the wall). Anyone else using this set up that has been able to get it to work?
