Hi!
Latest BSplayer's version doesn't need VobSub to be installed on your computer, you have to go in Subtitle preferences (
CTRL+P then
Subtitles), select VobSub tab, and select the option "Enable VobSub support" (maybe also check the option "Load subtitles into memory").
Then as you did before, right-click on Movie window and select "Load subtitles..." menu item. There you can select the desired file for subtitles.
Once the subtitles are loaded (you should have now enabled subtitles items in BSplayer's menu, if you have not, then the subtitles were not properly loaded), try changing subtitles position on the screen through the subtitles menu items (try automatic position, and if it doesn't work use custom).
If subtitles are properly loaded and you still can't see them, try to select the option "Draw subtitles to Overlay surface" in Subtitles preferences.
To know more on loading and manage subtitles, read BSPeter's "READ THIS FIRST BEFORE POSTING" post (aka Help2Help) item
(9).
I hope this could help you, and I hope to have not write nothing concerning you "nothing" thing
:P
