Any ideas if this is possible to hook an xbox up this way.

I have a super old tv, one of the ones with the channel knob that only goes from 2-13. It has to be hooked up with a super old cable box. There is an av input in the back of the cable box. I hooked up the cables in there, but there is not video/input button obviously so I was wondering if it had to be on a certain channel.

Any ideas??

I think it is kinda odd your cable box has a imput in. most only have a imput out. Im guessing that's what yours has. What about a rf adaptor? Ive seen rf adaptor boxes for xboxs for 5 bucks at walmart and toys r us.

Yeah, I'd say your only bet is an RF adapter. The video quality is going to suck though

i'd say RF also, but if you box has an input try channel 00 or go down on the channels until av1 comes up. i had a cable box like that about 15 years ago.
