Please use this thread to describe your system problems and the firmware/version number of your machine. The DAV-S (550 and 880) suffer from subtitles bug with firmware version 1.07, and is apparently not field upgradable. [Subtitles randomly come on, but almost always on layer change.] There is also a video level improvement which was made after the V1.07 units. I have a DAV-S550 which is new stock (received by Sony Hong Kong in mid-December) v1.24 which has a video glitch on layer change problem: Using the component/progressive outputs the ?last frame? of layer 1 stays on the screen until the ?laser refocuses on layer 2? of an (NTSC) DVD. You can find your version by: 1) eject disk 2) press stop and display on main unit while turning volume knob to the right (e.g. clockwise). Exit the service menu by standby on the remote, or power off. If your machine gets upgraded by Sony, please tell us the new version number. Thanks, Sam P.S. presume similar results with DAV-S550, DAV-S880, DAV-C770, DAV-C990 .
