How do I hook up a DVD recorder with no Coaxial cable inputs/outputs to an old...

You need an RF Modulator. Like this: http://www.walmart.com/ip/GE-RF-Modulator-Video-Converter/16561369

DVD player output to the TV input

Then plug in the Aerial to the the aerial DVD input

Your question suggests that both your DVD player and TV are both pre-digital, which could cause major problems for receiving some Channels

If you are using your DVD recorder as your Freeview receiver, this is not a major problem
It can deal with this easily
