To answer my own question and to pose another, it seems that the NEC DVD RW ND-4570A that I have can record to any format, although it struggles with dual layer, which I'm not using. My question is why can't I copy anything to disc? When I try copy and paste, I get the following message: Problem copying. Windows encountered a problem when trying to copy this file. What do you want Windows to do? There are two buttons: retry and cancel. Retry just brings up the same message.

I bought some blank DVD's but they don't work. I guess they are the wrong format. Thanks Barry
