I have several DVD's with many episodes of a show on each one. I would like to pull my favorite episodes from each DVD and then burn one DVD with all of my favorites. I can rip the episodes I like, but they are placed in VOB files and then when I pull epiosdes from the other DVD's they are placed in VOB files named the same (VOB_1) so they are overwriting the other episodes from the other DVD. I have DVD Shrink, DVD Xpress, DVD X Copy, DVD Decryptor programs. What can I use to make this compolation DVD? Thanks!
