Player use "local configs" for remember your setting for every opened file, so you need to set your video only for first time, in next time player automaticaly opens video with last time added subtitles or other settings (like subtitles shift, position ..)

If you want add subtitles to movie - drag them on player or video window, or use command for opening "open Folder(s)/File(s)" from PopUp menu or skin button. Player automatically detect taht opened file is subtitles and add them to video instead of opening it as new file.

All translations available in release time of latest version are included in instalation. Only updates or new languages are in download page.
If you looking for some other language, which is neither in instalation, neither on downloads page, then it is not available now.

Downloaded file *.*.lng just place to directory ..\MV2Player\Langs\ .

Visible pages in Options are depend on User Level setting (Options-Player-User Level). For see all available pages turn User Level to Expert.

If file is *.mvz or *.sk2 just copy it in skins directory - ../mv2player/skins/ . If file is ziped, then unpack it this skins directory.

One way is using pop-up menu command "Open File/Folder". Other way is using Drag&Drop file/folder on MV2Player.
