One RF on TV - what do I need for OTA HD and regular cable?

[Chad B]

I have a Samsung 37 inch LCD TV that only has one RF jack on the back for coaxial. Right now, my Charter cable receiver (digital, standard) is going to it. I have an indoor antenna to pull in the OTA HD channels. I've heard that I would need a A/B switch (Radio Shack has a remote control one) to make it work. The only other jacks on the back of the cable receiver are yellow, red and white. Can I use those instead for the cable?
Is it possible to run the cable through an old DVD player as the tuner?

Does your TV have a jack marked ATSC? If it does then hook your TV antenna there.

And the old DVD player may work until the 17th of this month (if your in the US) that’s when all the old analogue TV stations shut down and go digital.
