copy vob files

[checkmate]

How were the vobs created?
Which program was used?
I normally use virtualdubmod or virtual dub to extract the audio
depending on wether it's ac3 or not.
TMPGenc to encode the video.
IFOEdit to multiplex them back together and the same program to
produce the vobs.
IFOEdit again to turn the vobs into a image file and then DVDDecrypter to burn the image to dvd-r.
