This is likely due to heat expansion (turned on) and contraction (turned off).

I have a solution but it is too much info for this tiny screen they have, and there is no support for photos. So, unfortunetly I have to send you to my photobucket account where I posted scanned pictures of the "Acual Manual" I hope the website doesn't get banned. Here are the five pages you'll need to set up your giant remote:

0178 will work but you have to keep the set-up button pressed down for more than a few seconds after you press TV on your cox remote. (You will see the tv button light up 2 or 3 times after pressing it and holding the set-up button down)

Here are the instructions for auto code search from the Omnitech manual:
Automatic Search
There is another way to set up your controller, that does not use the brand code lists. You can let your
controller search through all of its available codes automatically in order to set the connection to the
target device. To do this, follow these steps:
1.Turn on the target device.
2.Point the controller at the target device and press and hold the Code Search button for around 3
seconds, until the LED light stays red.
3.Next select the type of device the target unit is by using the Cable/TV/VCR/DVD/Sat Buttons (i.e. if
it is a TV that you are trying to control, press the TV button). The LED light should then blink once,
then stay red.
4.Press the On/Off button on the controller slowly and repeatedly until the device you are trying to
connect with turns off. (Note: the LED light will blink each time you press the On/Off button). When
this happens, press the ENTER button in order to store the code and the LED light will turn off.

Vizio recommends using code 11758 or 10178 for Cable/Satellite universal remotes that use five digits such as DirecTV. For four digit Cable/Satellite universal remotes , use 1758 or 0178. For three digit Cable/Satellite universal remotes, such as Dish or Echostar, use 627. These codes typically make the Power, Volume and Mute functions work.
