I've just connected an x box and dvd player to above amp and Plasma... Whereas before the dvd was not going through the amp but direct to the plasma. Now because I'm a lazy b I just want to ask will it aversly affect the video signal on NTSC DVDs as the amp is Pal? The picture on the disc I've tested looks fine... But maybe it's me... I felt it was a little softer. The DVD player by the way is the Philips 962sa Prog scan. So rather than fiddle I thought I'd ask the experts.
