I am somewhat confused because if I set Av input to RGB ,as suggested, I get a blank screen on av1 ( extn 1) and yet my digibox is connected to av1( RGB) whilst the dvd recorder is connected to av2( video, svideo). On extn 2( av2) I get a picture but no screen messages appear on screen although they do appear on av1(extn1)?? However I do get a picture on extn1( av1) if I change av2 input to video. This suggests that my pictures can only be in composite and , indeed changing my picture settings on my sky+ to Pal from RGB produces no discernible changes either to extn 1 or 2 As the dvd is connected to av2 I would have thought all screen messages woukld appaerer on extn 2? Could you please advise? Finally which ext link setting would you use - 1 or 2? Not sure what the difference between them is.
