CloneDVD Before you begin［取自CloneDVD 1.1.6.1說明］

NOTE: CloneDVD does not backup copy-protected DVDs! Many DVDs are Content Scrambling System (CSS) encoded, which is a copy-protection file system. If a DVD is CSS-encoded then the DVD reader will refuse to access the disc. Therefore CloneDVD cannot read the files and make a copy.

注意：dvd 片子若有css保護，CloneDVD也沒法度，是嗎？
