I am no expert but Ibelieve the following to be correct.
I assume that your DVD recorder has an analogue tuner. Does it have any A/V input facilities such as Scart? If it does, and your TV has A/V outputs, you should be able to connect the TV to the recorder via A/V and record. If your TV does not have A/V outputs but the recorder has inputs, you could get a cheap freeview box and use that to record digital programmes from.
