I have copied a DVD of an old family video to my computer but am having trouble playing or converting all of the video content.

If I open the DVD directory in VLC or MPV to play it I can see that the video is 1h46m but it will only play the first 14m53s, which seems to correspond with a ‘chapter’. If I open the directory in Handbrake it will detect the full video length of 1h46m and a total of 8 chapters but will only convert the first chapter. Ffmpeg will convert the three main .VOB files to .mkv but the output files only add up to 30m or so of video, which is an improvement over opening the DVD directory in a media player or converting it using Handbrake but still doesn’t pick up the full video length.

What, if anything, can I do?

Thanks
