Tiro, et al...When I bought my TV tuner card, the directions had me connect a gray cable (antenae) to the card. In your last pic above, you can see it going under the black tape near the red wire on the left. Does your gray wire and this gray wire go to the same thing, the CATV input? I am wondering if the two cards could be switched around, and both wires are going to the same place. I would really hate to connect the wire as you suggest and then run the CATV and damage my internal wireless card.
Can anyone else shed some light?
