DTS means Digital Theater Sound all dvds do not have this option most use dolby digital 5.1 in order to use DTS your equipment must have a decoder for dts
I would remove the DTS audio stream unless you have a DTS decoder surround sound system. The dolby 5.1 stream will suffice for most and if you don't have a surround sound system the 5.1 stream will be down mixed to 2 channel stereo. Personally I like the DTS audio stream.
I also prefer the DTS audio stream. If both DD and DTS are on the disc, but I only have room for one, I'll take DTS everytime. I'll buy the DTS version of a dvd (ex: Gladiator), before I will the DD also. If you ever plan to have surround sound, you may want to keep it......
