My guess is that if it doesn't have the dts badge right on the front face plate / it don't do dts. If you have software where there is a choice /once you make the 'yes' for dts there is the dts 'logo' many have the piano / with chalk flying / it you see that then the ans is 'yes' ---It ain't the end of the world if you don't. This should at least clear up whether you do or don't.
