b) a SCART cable connected between a socket on the TV which supplies an output from the TV tuner (see the manual).....
c) .......to a socket on the VCR which accepts an input. If the VCR has not got SCART, then you may need an adaptor
d) the VCR set to record from the AV (Ext) input used in (c) above
