You can access the EZTitles Plug-in's unique presentation controls by clicking the Browse button (the one with three dots) at the EZTitles plug-in/Configure section as described:
After that a dialog with additional options shows up to help you present and adjust the subtitles in the best fashioned way.
All the available options are separated into several sections which will remain the same with the only exception being the bottom one which concerns the file encoding.
It will accordingly change for any text based file, like .txt, .ssa, .das and etc, or .PAC loaded.
The content of the dialog will also change accordingly to the Burned-in, Teletext or Closed Captions choice you have made and will be explained with the next couple of topics.
