OK, I\'ve got my fiber-optic line hooked up and selected in the \'system configuration\' of the PS2. My receiver is indicating that it is receiving an audio signal through the fiber-optic connection, but I\'m still not getting the dolby digital and/or DTS sound when viewing a DVD movie (I\'m getting regular sound, but my receiver isn\'t indicating that its processing a DD/DTS signal). What else can I do? Thanks in advance.
