As far as scart is concerned it needs to go:
1) Sky box (Video/VCR out) to DVD Recorder
2) DVD Recorder to TV

The picture above shows the Freeview box (number 7) going direct to the TV. So you could watch it but not record from it.
You would need to record from the digital tuner in the DVD recorder.
I guess the extra Freeview box does allow you to record one freeview channel while watching another.
Not sure if you have a Sky+ box but I would consider it, as with that you can record two channels at the same time, or record one channel while watching another.
All this is recorded on a hard disk in the sky+ box and can be saved, watched, and then recorded onto DVD if you want to keep it.
