Change links on DVD menu

[Mannish Boy]

Hi. I've ripped a DVD to my hard disk, shurnk it down to 4.4Gb, removed a bunch of extras, other audio tracks, subtitles and so on, but I've kept the menu structure because it's not a movie but six episodes of a tv series. The trouble is, the episode selection sub-menu no longer works. I'm assuming this is because there are now less vob files and they are labled differently (or something). If that's the case, does anyone know how I can edit which vob files the episode selection menu (and it's chapter selection for each episode) uses? If that's not why the menu isn't working, does anyone know why?
Other parts of the menu are still operating, however.
I ripped it with DVD Decrypter and shrunk it with Clone DVD.
Any advice would be well received!
Thanks in advance!
