My Sky digibox is connect to my TVs RGB scart socket. A DVD player which I used for MP3 playing through my 5.1 system is connected to sky digitals second port and via loopthrough-, when this dvd playerr is switched on, the sky box automatically switiches to the av channel. Now what I want is the abilty to manually switch back to the TV picture, so I can have the DVD player on with music playing but see the TV picture at the same time, good for parties etc.. How can I set this up. I use to have a humax pvr 8000t and I did this by pressing the DTV then SOURCE button. Please do not suggest I connect the DVD player via s video or composite, I WANT an RGB picture.
