These VOB files 'seem' to follow on from each other in a sequence, which when watched on a dvd player has been portrayed as the video that I am watching, and each VOB file plays 'on' from the other. I have previewed the VOB files in a media player and have discovered that VOB_3_0 through to VO_3_8 are all of a similar size of 1.3 gig each. Inside the Video folder I have files, they are an assortment of files and the main ones that I am concerned with are titled VOB. Maybe then I will rephrase my question without calling a file the incorrect name. Thats your answer? does it feel good to try and humiliate someone behind the safety of your computer screen?īe that my wording and or terminology is incorrect, your answer bears no meaning to the question, so why would you even bother? The time taken to make 10 keystrokes a few mouse clicks and then the bandwidth to upload your answer which was helpful in absolutely no way at all. I guess that the ultimate solution would be to add a DVD reader who understands the dvd structure as I this information is stored in the IFO file.

This would save the additional step of extracting the subtitles to IDX/SUB. However it would be nice if this information could be acquired somehow and written to the codec initialization part for the files to be editable by mkvtoolnix. While I understand that the CodecPrivate data is not direct available when reading from VOB files as this information normally comes from the IDX part of extracted subtitles in vobsub format.

Also editing the file with mmg/mkvmerge does not work because the existing subtitles are ignored and not written to the output file because of the same reason (Warning: matroska_reader: The CodecID for track 5 is 'S_VOBSUB', but there was no private data found). The header editor recognizes all tracks but mkvextract fails to extract the subtitles because of the missing data (Error: Track 5 with the CodecID 'S_VOBSUB' is missing the 'codec private' element and cannot be extracted.). The subtitles play fine in vlc but mkvtoolnix has problems with editing the file. When copying DVD subtitles from vob files into the matroska container the subtitles do not contain CodecPrivate data.
