just realised you said set top box. aswell you need to put this in first in the loop af aerials in front of the dvd then run the scart form that to tv in sted of form the video unless you have got three sockets on the back of your tv
Note. You don't want to be forever changing scarts. So you want a multi scart socet switching unit. These come in from 2 to 5 inputs to 1 output normally BUT NOTE you must get a switch one.
There some on the market with several scarts to one O/P but no switching and these do not work properly as two or more units all connected to the same scart circuit change to 75 ohm loading and the picture quality suffers.
With a switched unit only one input at a time is connected to the output.
The aerial goes from the wall to the Box, then on to the DVD, to the VCR and finally to the TV. That, I understand; thank you.
The TV has 3 scarts which are connected to the Box, the DVD and the VCR. I take it, from JACMAC, that the Box is connected to the DVD and VCR via a multi scart socket switching unit. This allows me to use the DVD or VCR independently and without losing picture quality. But does this allow me to transfer recordings from the VCR to the DVD? Do I need to connect the two directly, and if so, how? There just aren't enough scart sockets on either of them.
