The reason I have the wiring as described (yes, it is correct) is that my tv only supports RGB input on the AV1 input. Therefore, if I wish to get an RGB input from both my STB and Xbox, I have to run it throught a scart switch that supports RGB so I don't have to go fumbling around at the back everytime.
The DVD recorder does not support RGB, therefore it seems superfluous to put it on the same line. For simplicity it is kept on a different input.
If there is any chance of a short inside the DVD recorder, there is no way I'll be touching any scart pins as I don't know what sort of voltage is going to hit me. (You don't know my ex-wife by any chance, do you?

)
Thanks all the same.
EDIT: To XFS03, the problem shows up both with the remote and the panel button.
