Please excuse my ignorance !! I am using a Pan 42PV500, Pan EH50, Sky +, and a Sony STR DB940 amp and 5.1 spkrs + a video etc. The problem is that every time I want to change source I have to select via the tv remote control the colored buttons and navigate to either AV1,2,3,4 or C/PC/HDMI. Am I correct in saying that an AV amp will solve this by auto displaying which ever device I start playing? If so any recommendations of which to choose or anything soon to be available? Many thanks.
