TV TUNER HELP

This may be irrelevant, but I have a question about the TV tuner. I understand that you plug the tuner into the XB1 through USB, not HDMI. I have an Xbox 360 hooked up to my XB1 through the HDMI-in port. In order to play 360 games, I have to use the TV app,
and the TV tuner uses the TV app as well in order to work. I also understand that when you plug in the TV tuner, the OneGuide separates the TV tuner channels from the "HDMI content". My question is this: if I have a TV tuner with a coax cable connected through
the XB1's USB port AND an Xbox 360 connected through the XB1'S HDMI-in port (both at the same time), can I switch between my Xbox 360 and my TV tuner when using the TV app? Thanks for the help!

Is it the offical xbox tv tuner, i have that and it's working perfectly in the back USB port.

Try uninstalling and then installing the tv app while the tuner is in the back port, that might help.

The tv tuner works with open air channels in the US and Canada. This support article is all about
