I have been seeing these faint light-blue "shadows" to the right of certain images on my projector. Now I never saw these before so I am wondering whether it's my cables or something...I'm using a 480p progressive-scan dvd-player with component outs to the projector. How important are the cables? I'm currently using 3 25-foot RCA cables to connect the dvd-player to the projector so maybe that's the problem. Anybody else ever have this problem with progressive-scan component outs?? Thanks!
