I intend to purchase a Plasma screen and will initially use a Sky Digibox (Grundig GDS310), Sony PS2 and VCR (JVC HR6700S) as the video source equipment. I will also be purchasing an AV amp and it seems sensible to use this along with a sophisticated learning remote (to switch on the required source and select the correct input signal) as the "control centre" for the signal, ideally with a single connection to the screen from the AV amp. <br />Obviously with an investment of this magnitude I want to obtain the best possible picture from the screen, which as I see it means supplying it with the highest quality outputs from the source devices, meaning VGA from the Digibox and PS2, and S-Video from the VCR. However I have found no AV amp capable of switching RGB through it.<br />I am by no means an expert on this subject but know enough to be dangerous! I would appreciate any advice, hence this post.<br />Is their any alternative to connecting each video source directly to the screen (messy by comparison) and using the AV amp for sound only?<br />I have been advised that a "Line Doubler" could be used to convert the output from the AV amp to a non-interlaced (progressive scan?) RGB signal which would be supplied to the screen via a 15pin D-sub VGA connector. This would mean using S-Video from all source equipment, switching it through the AV amp before passing the output S-Video signal through the Line Doubler.<br />Would this arrangement give a superior picture to providing interlaced RGB signals from the Digibox and PS2 and S-video from the VCR?
