Unfortunately, DVD Copy cannot duplicate or reconvert copy protected DVDs. Corel has to follow standards set by law and respecting the copy protection for DVDs is one of them. DVD rip software which copy protected DVDs are actually illegal and are categorized as tools for piracy. So I won't be able to suggest one for you.
A disclaimer is available at the Corel's website and the boxed copies as well. The disclaimer reads: You may use this software in copying material in which you own the copyright or have obtained permission to copy from the copyright owner.
If you do not own the copyright or you have not obtained the permission to copy from the copyright owner, you may be violating copyright law and you may be subject to claims for damages and/or criminal penalties.
