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?
Your cable box will have A/V out. Your DVD player should have component out, which you can connect to another TV input, using the composite for the cable box. Or use a A/V selector to share the one input.
No! That is composite video and audio and is a totally different signal than the RF. Run the Charter output into one side of the A/B switch and the antenna in the other side and then take the output to your TV. Use only RG6 cables which you can get many places.
As long as your TV has a composite input (yellow/red/white), and your cable box has composite outputs, I don't see why you can't hook them up. Then run you OTA antenna into the TV's coax connector. You may need to use the TV's menus to select between antenna and AV inputs, unless the remote control lets you do that source selection - many do. DVD players don't have tuners, only DVD recorders. Your HDTV should have NTSC/ATSC and QAM tuners.
