Looking to get an AV receiver/Amp. Am new to all this and have got myself all confused. 1. What is RGB? What do the actual connections look like? I'm fairly sure it's not the yellow, red and white connections I've got on the front of my TV. 2. My wife will kill me if I get something that requires having to change the AV receiver setting each time she uses a different source (sky, vcr, cd, dvd etc). Is there anything that will automatically 'switch' to the relevant settings depending upon which source it is getting data from? 3. My Tv has got 2 scart inputs at the back, and s-video as well as the yellow, red and white conenctions at the front. Is it going to be possible to have a VCR, DVD player (also used as CD player) and Sky all going through the receiver and into the TV? Thanks.
