I have been reading through several of the current threads on this forum. They are very similar to a problem that I currently have so hopefully someone can give me some advice. I have a Hitachi PMA400 connected to a Sony DAVS550 Home Cinema system via 3 Component Video leads. The picture is great when running DVDs. I want to connect a Grundig digibox up to the current system but I don't want any more leads connecting to the plasma. I want to run everything through the 3 component video leads. Does that mean I have to connect the Grundig to the Sony ? The only way it appears that I can do that is via the Scart on the Grundig (TV Out) to the 3 phono sockets on the Sony (Red,White,Yellow) using a Scart to Phono converter socket supplied with thenSony. However, that doesn't work. Can anybody help?
