DTS Issues

Hey guys, when i rip a film using ANY s/w DVD2ONe for example, if i select DTS i get NO AUDIO in the output, the original films play perfectly, tried a few, but i cant get ANY program to work, is there anything special you have to have installed on Windows XP to allow this??
If i use smart-ripper on the compiled film after the rip, there is NO audio stream :frowning:

Please help, this is really baffling me!
:rolleyes:
