This is already wrong. The VOB files do not map directly to the video
parts of the contents. If you do that, you will get also all the menu
crap in your resulting file.

Also, the subtitles palette is not in the VOB files.

You can generate a concat script to access the DVD hierarchy correctly
using the dvd2concat script in the tools directory.

It is entirely possible that doing so would fix your issue.

Also, do not re-encode the subtitles, use -c copy, it will be more
