I successfully copied a a DVD by using mac the ripper, DVD2one, and then finally Toast 6. This was months ago and have just recently gotten back to copying. But now everything seem to go fine until I get to the last stage, finishing with toast and I get a message that says "sector 2193248 is unreadable. Verification failed". If there is anyone out there that has any knowledge of this and can get me in the right direction please help........Oh! I've been using TDK DVD-R media. Thanks!!!!!!!
