I have a problem (that is surely fairly common) in that with a recent purchase of a DVD player I have 2 devices capable of RGB output, the other being a Sky Digibox, and only 1 RGB input on my TV. I was going to use a SCART switching box to plug both devices into the SCART input, but is this the best option? How much better will the RGB output be over V-S on DVD? I do not want to switch to PAL from my Sky box as this is noticbly inferior. Any advice would be welcome before I buy all the cabling.
