Successfully ripped brand new DVD to folder on hard disk to later convert movie to m4v using HandBrake for Mac. Conversion to m4v using Handbrake was successful, but chapter 1 of movie is missing (the first 14 minutes of movie). Subsequently tried copying movie to hard disk using CloneDVD2 and encountered same problem — even CloneDVD2s preview skips chapter 1 and goes straight to chapter 2. Is this a copy protection issue? Defective disc? Please advise.
