Subtitles and audio from VOB - changing not working

[Jedrek]

I have the latest version of BS Player, and noticed that it has errors that were not in the earlier version of the program:
The errors do not occur when you open a DVD from the "Open DVD" does not matter whether the recorded disc or hard drive. Problems when you want to open the player BS Player single VOB file. Of course, impossible to open the file, but there are problems:
1. The problem with the change audio tracks. Menu / Audio. All fields except EQUALIZER are gray, nothing can be changed, are not recognized language audio tracks.
2. The problem with the change subtitle language. Menu / subtitles. Whether you choose a PRIMARY or SECONDARY, we always get the "undetermined". Even after selecting no subtitles on the screen does not show up. Both the choice of audio track and subtitle as is done in the VOB file.
Please check and rectify the error.
