I have a problem with my Marantz SR5200, it seems that it takes a few seconds for the reciever to "lock on" to the dolby digital/DTS track before the sound comes out the speakers - it's especially annoying while navigating DVD menus where I miss out on the transition sound effects, when i pause a movie and press play again it does it (2 second silence) and when the DVD layer change happens it does it also, it even does it in the THX audio test where it puts a test signal through each speaker. I am using digital coaxial connection from my DV4100OSE DVD player. I tried a different DVD player and it makes no difference. I phoned Marantz UK and they said this is "normal", but i'm really quite annoyed with it. I've already had Sevenoaks replace my reciever for a new one that came in only last week to see if it's been fixed on newer units. My friends Sony reciever doesn't do it. Is there anything I can do to fix the problem myself? I'm happy to take the cover off and modify what's needed. Failing that i'm considering selling it and getting the new Sony reciever. Please help!!!!
