It doesn't matter what connections are on the TV. For that matter, there doesn't even have to be a TV in the same room; a DVD recorder makes its TV recordings from whichever tuner it has fitted i.e. Freeview or Freesat, but it could just as easily be a cable tuner for Virgin if someone were to design it. The point is that a DVD recorder operates independently of any TV to which it may be attached. One may well use the TV to view the EPG for programming, but that's just a point of convenience to make the act of programming easier in itself.
Those older analogue DVD recorders from roughly a decade ago did have external inputs. I have a Philips DVDR520H which has a (now defunct) analogue-only TV tuner but also AV inputs in the form of composite, S-video and SCART RGB, so it could record from an external source. However, there aren't many (if any?) modern TVs that now have an analogue AV output that replicates what is seen on the TV screen as a source for an external recorder. Nor am I convinced that those few remaining DVD/Blu-ray recorders still in the market have the sort of analogue inputs necessary to make use of a TV as a source if one existed. In sort then, the idea of a TV as a source for making recordings on to a modern DVD recorder is a dead duck. Don't waste your time.
