Modern day freeview boxes rarely have A modulator in them so you can not tune it to a channel on your tv it must be connected using scart lead.
Most freeview boxes have 2 scart sockets one for VCR & one for TV plug your scart leads in to the scart sockets of freeview they will be labled TV & VCR.
The scart labled TV goes to scart socket on the TV labled AV1 or 1
The scart labled VCR goes to scart socket on VCR labled AV or IN
Now the aerial leads From wall socket to ANT in on freeview.
Then from RF out on freeview to ANT in on VCR.
Then RF out on VCR to ANT in on TV doing this will enable you to put TV on 9 to watch tapes.
The final scart will be from DVD to TV socket marked AV2
You will need to put TV on AV channel to view freeview.
To record freeview you must put VCR to EITHER line.av,aux. it will be one of those different manufacturers call them by varying names.
I have done this banking on your tv having 2 scart sockets if it only has 1 let me know & I will tell you how to wire it differently.
Please state make & model of TV set & VCR & what connections are available EG scart, Phono, Svhs etc.
