Encoding from FrameServed Files:

After you have successfully copied your DVD Movie VOB files to your local HDD, you can now start the encoding job itself, however, some of the encoders cannot access the VOB files directly, or they can only load a VOB file at a time, for those type of Encoders, there are programs which create a "dummy" file which allows access to all the VOB files, however, there are even older Encoders that don't support the frameserving files, and for those, you create an additional "fake" AVI file which is supported, and that is how they can access the movie.
