Heres my dilema. I have a TV tuner I use to take screenshots of videogames. However, there is about a 3 second lag, i guess because the tuner has to convert the analog signal to something for the computer. Anyway, because of this, its difficult to actually play a game and get to certain portions of a game and take screenshots of it. So i had the idea of splitting the video signal that a given console gives off, sending one cable into a tv and another into the tuner, so i can play the game, and take screens of it. Is there some way I can do this?
