The DVD recorder has an analogue tuner only; so yes, that's what you'll normally be recording by default.
However there will be an external input SCART (labelled 'EXT2', I think), at the back of the recorder which you need to connect with another source - e.g. a VCR, Virgin Media, or Sky box - in order to record something from them. You could connect your TV up to this, but for it to work, you have to find some way of getting the TV to output a signal to the recorder's EXT2. Normally TVs are input only, but some have a bi-directional SCART socket which can be configured to sent signals out. You'll have to check your TV manual to see whether it is possible and how to do it.
