DVD Ripping

I had to rip a movie trailer to post for a promotion at work and tried to use this guide:

When using VLC portable, it crashes no matter what video codec was selected.

I then installed VLC using their local-installer, and it also crashed using mp1v as they suggested (just for reference in this post.) I then selected encoding using mp2v and it worked. So I tried VLC portable with mp2v and it also crashed. I then assumed that VLC portable has a ripping issue and may be looking for libraries (?) just a theory.

Ripping with VLC portable would be ideal if you guys can figure out how to fix it.
Thanks! =)
