Tunerless DVD player/VCR combo question

If the TV has the red/white/yellow connectors on the back, then yes it does.

If not, you'll have to get an RF convertor.

I'd kind of like to explain what's happened since my last post. It was a friend of mine who bought the Magnavox DVD player/VCR. On the back of his TV was the red and white audio jacks but instead on a yellow video jack there was a weird looking jack called an S-Video jack. The front of his TV had all three A & V jacks (red, white, & yellow). I wrestled with the whole contraption, the TV & the player/recorder, and for a brief instant was able to get a DVD to play for a couple of seconds before turning it off. After fumbling with the machines another couple hours, I was unable to get even that much out of it. My friend had a technician from Cox Communications come over (the visit cost my friend $30). The Cox guy was able to get the machine to play back disks and/or tapes but then left without getting the VCR part to record. The last thing I told my friend was to contact Cox and tell 'em their guy didn't finish the job he was paid for. (I haven't heard from my friend for a couple of days.) (P.S. He doesn't have the owner's manual or original remote that came with his TV, the TV was a used one that was a gift.)

The "S" video jack is a higher quality than the A/V in. Not quite HD but very close

Some set-top boxes have two sets of audio and video outputs. Presumably the idea is that you can feed one set directly to the TV, and the other to a VCR. If the cable box has a spare set, connect it to some inputs on the VCR/DVD combo.

If the cable box only has one set of outputs, you should be able to pass it through the DVD/VCR combo. box -> DVD/VCR -> TV

Select the proper input on the TV so you get a signal from the DVD/VCR, then change the input on the DVD/VCR to get the cable box.

Or just invite a technically inclined friend/co-worker over and pay them in beer and pizza or sexual favours, as appropriate.

Yeah pretty much that ^

Save yourself the headache.
