Hey Terry! Thanks again for the help. I was able to copy a dvd once befor using this method. This time, however, it didn't work. The message that I keep getting is to put in a blank disc. (that's from the destination drive) I tried to configure it different ways: changing the 'source' and 'destination' designations, but nothing works. I've even uninstalled and re-installed the Roxio software TWICE, but it won't work.
Anyway, I was able to copy the dvd's by first burning to the hard drive, then to disc. Before you posted your information, I used the search function, and after scratching my head and trying several different things, finally found the files and deleted them.
Your way would've worked, I'm sure, so I'll make note of it, and use it next time I try this. Thanks so much for your suggestions. Take Care!
