I am converting a bunch of clips to iTunes using Toast Titanium. I guess it can work with the Elgato Turbo device because it basically displays an ad on it's update screen. I searched for it on the net and, well, I'm confused. Is there more than one of these things? I see one on Amazon for $75 or so (list is $150). But there are other products that keep coming up like a tuner and some other such things from the same company. Help!
