A lot depends on what connectors you have available on the TV, Digibox and VCR
I would try the following:
-> RF aerial to digibox RF input
-> RF aerial output from Digibox to VCR digibox RF input
-> RF aerial output from VCR to TV RF in
So far this will allow you to watch analogue channels on your TV, and record analogue channels on your VCR. You chould also be able to tune a channel on your TV to pick up the analogue output of the VCR to watch recorded videos.
-> Digibox output SCART to TV input SCART
You should then be able to watch all freeview channels by switching to the AV input on your TV.
If you then have other connectors free you could try:
-> VCR output SCART to TV SCART (assuming TV has 2 SCARTS available). You should then be able to watch the VCR via the SCART by switching the AV input channel on your TV (this will give you a much better picture than the RF analogue connection.
Then if you have another SCART free on the Digibox and VCR you can:
-> Connect Digibox 2nd output SCART to VCR input SCART
This will then allow your VCR to record whatever is currently playing on the Freeview Digibox.
