I hooked up my Panasonic sky box to the AV2 input on my Pioneer DV737 so that I could use it's RGB throughput into the AV socket of my TV. The Sky picture is miles better and auto switching is a breeze. I have one question. I am using an Ixos scart to feed in and a QED sqart to feed out. The QED does not transmit sound and is merely an RGB cable. Can the fact that the sound "can't get out" cause any damage and also does daisychaining cause any damage to tbe DVD player generally?
