I doubt those directions will help you. I'm guessing that those instructions create some kind of command code that when transmitted puts the DVD player into setup mode and then the #'s below activate region free. What you need is the actual IR codes that those commands send out to get into setup mode. You should ask someone who has done this to send you or post the Hex codes for this command. You can then input those commands into Neo using NeoHacker.

Alternately, you could download ProntoEdit yourself (its free) and follow those directions. Then just copy the hex code yourself.
