Hi there, I have a DVD-S400 and for some reason it has stopped playing some of my films, but only the ones on certain disks. Some slightly older disks (same make) still work, but the newer (from the same tub) ones, have stopped working?? Anyone got any ideas?? I seem to remember, there used to be a website that gave codes to do this kind of thing, but I cannot remember it!! Thanks for any help of info on this one. JDAML
