Though the TV has been great for the past 5 years or so as I embark on my initial home theater build.  I found all this info on Vizio descrete IR commands, or rather the lack of in this case.  I've tried going through some of the VIZIO stuff in a fully updated URC CCP program but nothing works so far.  Can't go out an replace it at this point.

I just thought i would throw this out and see if anyone had this model or any of the VO series that had found any descrete codes. 

Also if anyone has came up with any work arounds for switching inputs without descrete codes.
