Actually, I was NOT using the Record-Edit-Save mode, I was using the Record DVD mode. I didn't follow your advice. I really don't know enough about the workings of computers to feel comfortable uninstalling drives, although I do uninstall software. I did follow your instructions and go to the Device Manager, but only one of the DVD drives showed up, anyway.
I have given up, thrown away the $69.99 I spent on this product in Best Buy and, instead, bought a combination VHS/DVD player that will record from the tape to a DVD.
I will say before I go, however, that I found it difficult to locate this forum and fail to understand why Roxio does not supply the consumer with a toll free (or even a long distance) phone number to call in order to get help. I will never, ever purchase another Roxio product.
