About the VobSub subtitle format
VobSub or IDX/SUB is a subtitle format conformed by a SUB and IDX file. The SUB file is a binary file containing the bitmaps of the subtitle texts. The IDX file is a text file with a list of entries, one for each subtitle. Each entry has the time when it should be displayed in the video, a value indicating the offset into the SUB file where the subtitle text bitmap can be found, the subtitle position in the screen, and other information.
Since they're stored in separate files VobSub subtitles are very portable. This format can be muxed into MKV files easily, and many standalone DVD players support them for viewing DivX/XviD or any supported video file.
The only drawback from this format (like any other bitmap-based format) is that you cannot edit the subtitles with any subtitle editing program. You might be able to edit the position and display time, but editing individual text from these subtitles is virtually impossible. To edit the subtitles, you should first convert them to a text-based format, such as SubRip (SRT), using an OCR-capable subtitle ripper.
