So I got the Monoprice 4x1 switcher model HDX-401E and now my oppo DVD running through HK 645 works but the damn Samsung Bluray still does not?? I dont get it. I believe the model number is BD6500 on the bluray. If I turn on Bluray then switch it nothing happens, if I switch it first then turn on Bluray I get the opening screen of the player "welcome to samsung bluray" (or something like that)then the screen goes blank and thats it, no video or audio. I have tried different ports and switched cables. I only have the DVD and Bluray running through switch, Fios box has seperate feed to monitor. Anybody have any ideas?
