I saw over at vcdhelp that the same author for IFOEdit released DVDSplit v0.5. After seeing how easy it was to use and after the frustration I have been going though, I thought I would try it out. it's only $25. that's a lot less then DVDClone and DVDXCopy which aren't even out yet. anyone wanting to be able to back up their DVDs that are dual layered, this is the way to go. you will still need a DVD ripper, I used SmartRipper.
check it out at http://ifoedit.wh.fr0zen.com/dvdsplit.html
it's worth the $25.
