Purchased a Panasonic DB-35 blue ray player as i have a panasonic plasma TV and panasonic dvd 5.1 sound system. I have connected HDMI cable between BD-35 for the video and so that i get the sound from the 5.1 system have used an optical cable between the BD-35 and sound system. I have set the sound option on the BD-35 so that it will not use the HDMI cable and use the optical cable. so should work. Well i know it works as used a standard DVD and sound comes out of 5.1 speakers, when i play a blue ray disk will only come out of TV when i change the setting for sound to the HDMI cable. However not complicate it anymore but i will!! when playing blue ray disk i can get sound through the 5.1 system but only when i select sound with commentary option from the menu so i am puzzled as to whether its the settings on the player or the disk as i can get it working properly as said above when i use a convential dvd disk??
