Try this (I think!)
Aerial lead - Freeview box
Freeview aerial out - VCR aerial in (only needed if you want to record analog channels)
VCR aerial out - TV aerial in (only needed if you want to watch analog channels on TV)
(or just go Freeview aerial out - TV to miss out the VCR)
Freeview "TV" scart - scart splitter
Freeview "VCR" scart - VCR
VCR scart - scart splitter
DVD scart - scart splitter
Scart splitter - TV
It would be worth getting a switched Scart splitter to stop any interference:
