Yes, most DVD's are just DD/EX even though many of the films are DTS in the theater. It's more marketable for them to put in extras you can watch on the DVD than to allocate the space for the DTS soundtrack. Kind of a shame in my opinion. At least some DVD (like LOTR) are offered in DTS versions for those who want it.
