Friend has just got a Tivo, and would like to know if this set up will work for him: DVDplayer->Freeview aux->Tivo in->TV RGB Socket. All devices are RGB outputting. He only has one SCART socket RGB on the TV, and would like to be able to play DVDs through the TV using RGB. Will this let him do that? Will Tivo automatically pass the signal through when you switch on/start playing a DVD?
