I just get this system 2 week ago and it rock !  installation be quite easy , but the setup a little bit tricky as other reviewer state . you need to read the manual , especially to setup the dvd player so that it will output dt or Dolby Digital 5:1 signal to the A\/V Amplifier . once do , set the a\/v amp on auto detect and enjoy the show . you 'll see the a\/v amp tell you if it be dt sound or Dolby Digital , the little blue light be on , mean you be truly experience the movie as it be release in theater .  lotr , black hawk down , Matrix , Gladiator be movie you want to really demonstrate the quality of this system . lot of special effect , great sound , and a lot of rumble ...
