i've just started using TV 12 and i think is a great app!!!
i use it to "play" my online game running at home while i'm at work, and i have to say that everything works just perfectly unless for the directional buttons.
i'll explain it better, if i pres the directional arrow it actually works but what i need is to hold down the button otherwise it will not walk(in the game). So if you use them in the menu it works perfectly, but if i need to hold it down to move my character it will just do one step and stop.
