It's definitely the 8 one. I don't know the model of the TV right now, I'm not at home, but I've tried it on two TVs and they did the same thing. I'm also surprised.
I'm using version 2.5 final minidin 8, the cable I'm using is from a specialist cable store in Spain, I'm using it on an old tube TV, not one of the newer flat-screen TVs.
