MX Player possibly one of the best media player for all the Android operating devices. Here is how we can install DTS Codec to the MX Player because MX Player does not support DTS sound format natively. An error will occur if no codec are found, therefore you will only see the video but not the audio.
Here is how to install
1) Download the DTS codec file from HERE. Unzipped it to your phone internal SD
2) Bring up MX Player. Tap the Menu button
2) Find Settings
3) Find Decoder
4) Select Custom Codec and navigate it to the folder you put the DTS codec files. ( There will be 5 files altogether)
5) MX Player will auto restart. Your codec already installed.
