FF Multi Converter - How to get subtitles also

I use FF Multi Converter to convert VOB files to mp4 files. All works fine however there are no subtitles included in the mp4 even if VOB has them.
I read on FF Multi Converter that:

"VOB and a few other formats do not have a global header that describes everything present in the file. Instead, applications are supposed to scan the file to see what it contains. Since VOB files are frequently large, only the beginning is scanned. If the subtitles happen only later in the file, they will not be initially detected.

Some applications, including the ffmpeg command-line tool, can only work with streams that were detected during the initial scan; streams that are detected later are ignored.

The size of the initial scan is controlled by two options: probesize (default ~5 Mo) and analyzeduration (default 5,000,000 Ás = 5 s). For the subtitle stream to be detected, both values must be large enough."

What should I actually do when I use FF Multi Converter (as there are no options in the menu to change the settings referred above). When I convert VOB to mp4 I just add the VOB file in the application then click convert...

Never heard of FF Multi Converter, but I use a cool program called Handbrake.

Have you tried HandBrake? HandBrake can add subtitles to mp4 and mkv files from vob and dvds. The subtitles can be either hard coded into the videos or can be toggled on and off ( soft subtitles ).
