The answer here is a bit murky. On the one hand, industry heads like DVD manufacturers and movie studios call the copying of DVDs illegal because it infringes upon copyright law. On the other hand, the public cites the Audio Home Recording Act of 1992 as their justification for copying DVDs. This Act states that it is perfectly legal to copy a media source the you have purchased for the purpose of a backup or replacement copy. Currently, the studios and manufacturers are making their DVDs and CDs as hard as possible to record so that they may not be copied. However the DVD burning software industry has found ways to circumvent these extra measures taken by studios. So the answer is: DVD copying is legal if you are owner of the DVD and you make a copy for your own personal use.
