Set Top Box for TV Tuner Box?
 

While people LOL at the ancient-ness of the set top box, I recently got my TV Tuner Box working (w00t!) and was thinking of trying to improve the picture quality of what it is getting now.

For those who helped or read my old thread (http://www.gamingforce.org/forums/he...tml#post492059), I actually managed to make it work. Apparently the VGA-to-VGA cable was dodgy, and I wasted an assload of money to try to get it work. Blah.

But now that I got it working, I was wondering: Would I be able to use a set-top box as the "antenna"? The antenna I have is sufficient, but it would be nice to have watchable TV. Is it even possible?

I have no idea of what set-top boxes are like, only that they can make any TV receive digital signals. If this were the case, would I be able plug it in this little doobie-whacker?
