Re: Visio tv . . .
Ironically, all four of our HDTV's (2 in the house, 2 in the RV) are all Vizio's!
We have Direct TV at our house, but not in the RV . . .
But in the house we have to push the power button twice to activate both of our Vizio HDTV's . . . and our JVC, Magnavox and Admiral non-HDTV TV's to turn them on when using the Direct TV remote controls.
