I think that many people have never encountered this problem: received a set of DTS DVD on DTS DVD player, but no sound come out. Indeed, the DVD drive, says that it can play DTS (with DTS logo on the front), why there is no sound?
When a DVD player says that it can play DTS (has the label "DTS Digital Out"), this means it can read the DVD disc and stream through your port of "digital out" (on the back of the DVD player) to the AV receiver. So that you have an AV receiver (that is connected to the DVD via an optical or coaxial digital cable) to the DTS stream out, decoding and the production of your 5.1 speakers. That is to say will have that a DVD player with digital output DTS is meaningless, you also need a capable AV receiver of DTS. In summary, you must pass several to hundreds of dollars to get the AV receiver.
As the mention to the DTS DVD player, I must say something about the audio codecs DTS. DVD of film music and allow delivery of DTS, but DTS audio tracks has not existed in the original DVD specification (1997), therefore the first DVD players did not recognize at all DTS audio tracks. The DVD specification was amended to permit the Optional inclusion of DTS audio tracks. The DVD title must be one or more primary audio tracks in AC-3 or LPCM format (in Europe , MPEG - 1 Layer 2 is also a format of the main runway allowed). The DTS audio track can be selected by the user. Many modern DVD players can decode DTS natively without problem. But some are in need of an external decoder. This is the reason why a reader DVD of DTS, says that it can play DTS, but no sound will come out.
