CloneDVD2, DVDNextCopy, DVDFab, should not cause you any problems. I for one will not use DVD43 so I can not say for sure if having it installed will or will not cause you any problems.
You might want to uninstall DVD43 for now and give AnyDVD a trial run; AnyDVD will work with most programs except FAB. but you can disable AnyDVD when you trail DVDFab.
Good luck and happy hunting for that perfect program.
