I'm not quite sure what you are talking about here. DTS is a form of audio that is used in some dvd videos, and is quite common in blu ray video. DTS audio could also be found in the now obsolete format called HD DVD.
DTS audio found in dvd video is quite limited in specifications, 48 kHz or 96 kHz sampling rate, 2 to 6.1 channels, Half Rate (768 kbit/s) or Full Rate (1,536 kbit/s)
DTS audio in blu ray can be Full Rate, or can be DTS HD Master Audio, which is a lossless format. DTS HD MA is becoming the most commonly found audio format in blu ray.
If these are blu ray disks, you'll need a blu ray player or a blu ray drive in your computer. It is possible to convert blu ray to dvd-video, to play them in any regular dvd player, but you will still need a blu ray drive and a decryption program to get the videos onto the hard drive of your computer first.
