Some DVD's have a stereo 2-channel mix (Dolby Digital 2.0), but none feature a Dolby Surround or Pro Logic Surround option in the menus. This is because all DVD players can submix the 5.1 Dolby Digital track and output a Dolby Pro Logic Surround signal through the analog 2-channel outputs.
Dolby Digital is a catchall term which includes Dolby Digital, Dolby Digital EX, Dolby Digital Live, Dolby Digital Surround EX, Dolby Digital Plus, and Dolby TrueHD.Dolby Digital (AC-3) and Dolby Digital TrueHD (THD) is more common in cinemas, and far more common in homes.DTS also has several variants- DTS, DTS++, DTS-HD, DTS-HD Master AudioDTS-HD Master offers higher data rates than Dolby Digital TrueHD, and this has led to unfounded claims that DTS is better than Dolby Digital in sound quality.However, under identical mastering conditions, the two systems are indistinguishable from one another, both being lossless formats, are bit perfect when properly decoded into Lossless PCM raw audio, producing exactly identical audio.
Many surround receivers have surround simulation capability, however this is not true surround sound. Two-channel analog outputs from a DVD player can be decoded to 3 or 4 channel Dolby Surround (not the same as Dolby Digital or DTS) using the same surround receiver.
