So, my TV doesn't have a 3-prong thing in the back of it to plug in my PS2, but my AT&T Uverse box does. Anyone know if theres a way I can plug my PS2 into the cable box then have it run to the TV and work?

I tried looking it up but failed. 8(
I'll probably just go out and buy one of the screwy-in adapters if I can't do it, but I'm tryin to save every dime I can
