On Windows, get FFMPEG from here:
https://ffmpeg.org/
Copy and paste this in notepad, and save as a *.bat file to execute:
@echo on
copy /b "VTS_01_1.vob" + "VTS_01_2.vob" + "VTS_01_3.vob" + "VTS_01_4.vob" + "VTS_01_5.vob" "input.vob"
ffmpeg -i "input.vob" -vf yadif -c:v libx264 -preset fast -crf 15 "output.mp4"
exit
Of course you'll need to change the parts you want to combine and convert (VTS_01_1 etc)
