You've already posted so many topics. Keep to one topic. It takes time and people already posted in your first topic that they didn't have enough info. You need moonshell (DDTT version) and all you need to do to play music is to drag and drop MP3s to any folder and use moonshell. To watch videos a more complicated process and you will need to convert with BatchDPG or SUPER.
I believe the DSTT moonshell is in the downloads center or on the DSTT website.
