DVD Subtitle Ripper for Linux If you want to convert DVD subtitles into text format (e.g. subrip format) or VobSub format this program could be useful for you. However, it is only one tiny tool that you need in the process of producing srt files. This software depends heavily on transcode for its input and is therefore part of the transcode package (see transcode's contrib directory). So, if you want to convert some subtitles, grap a copy of the lates transcode distribution. For srt file production the output of this program should be processed by some OCR software. For VobSub output no other tools are required.
