If your TV has more than one Scart socket, it would be very simple to use two VCRs with it. All you would have to do would be to buy an aerial splitter to ensure you could feed VHF TV signals into both of them. Then connect one VCR to Scart1 on your telly, and the other to Scart2. Use one VCR for switching TV channels, and use the other for recording.
But is there no digital terrestrial service in the Republic yet? It would probably be cheaper to buy a digital terrestrial reciever if you can!
to the forum by the way.
