If I understand what you want correctly, you'd like to be able to push one of three buttons to get Xbox, PS, or TV/cable respectively powered up with the correct TV and receiver inputs set.

You probably already own a remote that can do this job. The Comcast remote has the necessary setup codes, if you're willing to enter in a few numbers to assign particular buttons.

The more important question, in my mind, is does the TV have discrete inputs?  And do both the TV and receiver have discrete power on/off commands?

Here's how to test, assuming you have a Comcast remote with a red OK/Select button. Or you could use the Vizio remote for this testing, but it can't control your cable box.

Make sure the TV device is setup to code 11178. [If Comcast has grey button, use 0178.]

To test, press TV, then:

1) Press setup briefly
2) Enter in a 5 digit EFC
the component should respond when the 5th digit is pressed.

For the Vizio start by checking volume to make sure the procedure is correct.
Function EFC
Vol+ 00183
Power On 00087  (should leave power on if it is already on)
power Off 00216
HDMI1 00193
HDMI2 00191
AV1 00225
AV2 00223


You can also check the Kenwood using setup code 31313, 31570, or 31027:

Vol+ 60899
On 61115
Off 60987
Video 1 60755
VIdeo 2 60794

If these work, we can tell you more codes, and how to assign the code to buttons, and how to make a macro that will carry out the sequence of button pushes that your want.
