How can I set up the DVR to turn the TV on and tune it to the DVR HDMI?

I have had a few DVD players, the low cost type, each one of them when turned on it automatically turns on the TV and selects the HDMI port it is connected to.

I would like to be able to do the same with the DVR. When I turn the DVR on, I would like it to turn the TV on and on the DVR HDMI.

I figured if the cheap DVD players can do it, it might be possible for the COX fancy DVR to do as much.

After I watch a DVD and I want to go back to the DVR I have to find the TV remote and manually turn the TV on and then select the HDMI for the DVR.

A bit annoying, I was hoping there is a setting for that.
