The ini files which were made for MicroDVD aren't compatible with BSplayer. However,
HWmaker can make a "light translation" to an ini file in order to be recognized by BSplayer.
You can load it by using BSplayer (open file), by right-clicking>open with>bsplayer or with HWlauncher.
If you want to make ini files very easily, you can download
HWmaker.
