First off , let I say that I be satisfied with the system . it be not go to rattle the window or wake the neighbor - but for ordinary movie watch with clear sound effect it be a good value . I have have this system for about 8 month and very seldom use the dvd . last night we purchase lose in translation and the dvd skip during the preview , then the player refuse to load the dvd after I eject and clean the disc . long story short , I hack the system accord to matta2k 's instruction later in this message board and now it work perfectly . we 'll see if I be still satisfy at the end of the year .
