Harmony Remotes

[mlpoe02]

I bought a Vizio E422VL a couple of months ago and just got the Harmony One remote to control the whole system. Everything programmed without issue except for the TV. The Harmony software says it doesn't have a matching model number. I have been looking on different sites to try and find clues to get it to work correctly, and saw that Amazon has only been selling this model television since Nov. 9, 2011. Could it be that the TV is new enough that Harmony hasn't added the function for it yet and that it will come in time or am I stuck programming it manually? The only function I'm worried about is the button that brings up the TV's internet apps. Any help or advice would be appreciated. Thanks guys.

Just wanted to say I too get the 422VL and Harmony One recently.  I programmed my Harmony to E472VL, assuming the only difference is the size (E422 is 42", E472 is 47").  So far it works fine.
