I have been having repeat problems when trying to copy my home videos. Have only one drive, copies original to hard disc. When I put in a blank for the copy, I keep getting the message "insert a blank disc". I have tried different batches of blanks + and - R, and even RW. Same problem. The blank discs register very well on a friends machine and copy without any trouble.
What is or has happened?? Thanks for help!
