Welcome to the forum :).
What's the manufacturer and model of your Freeview box and DVD recorder?
Usually the generic setup is:
Aerial -> Freeview box -> DVDR SCART EXT2
Aerial -> DVDR RF IN -> DVDR RF OUT -> TV aerial in
DVDR SCART EXT1/TV -> TV
Then you can record from the Freeview by selecting EXT2 as the source for the recorder, and still watch TV analogue. You can't record both though.
The camcorder recording to DVDR depends on whether your camera is digital (DV) or analogue (Hi8 etc). Perhaps there's a FireWire input on the DVDR for use with a DV camera - otherwise you'll have to use SVHS or composite inputs for analogue.
