Hi, I have a Panasonic DVD player, with a DTS sticker on the front. It's connect to a Dennon receiver with DTS encoding through an optical cable. When I use a DVD that say DTS on the front I get Dolby Digital II. There is a little light that comes on for DTS and I have been unable to get it to work. Even by using different selections. Question being, is it working, or should I be doing somehting else? Thanks!
