Only 18 Minutes?

[Prongs]

Hey everyone. I'm getting this weird problem with my program. I only get about Eighteen and a half minutes of conversion with a movie that is, in actuality, about an hour and a half long. That may be because of my decrypter program, though. Has any of this ever happened to you? I'm using DVDDecrypter to actually rip the CDs, and Videora to convert them. Suggestions?

DVD Decrypter is relatively old and won't handle most modern protection schemes. It is no longer being developed, supported or updated. A new decrypter may be in order for some DVDs.

Do you have a suggestion for a better ripper program? What do you use?
