you have to be playing a disc that is DTS enabled & you usually have to go into the dvd's setup menu or language select menu & select DTS (instead of dolby). lemme think... I think "Master & Commander" is DTS enabled among others. Sony came out with a line of movies called the "superbit" versions, & they are all DTS enabled. you also have to tell your DVD player that it can output DTS because otherwise it will stay silent. Usually receivers are automatic & you don't have to tell them that they might be receiving DTS... they'll just pick up on it.
I really like my new Panasonic HTIB. It appears to be all that CNET said. HOWEVER I cannot get the Digital Optical audio to function from a Sony DVD with DTS and Dolby. I have tried two cables too.
Any advice on what to try? All help is appreciated.
