My laptops drive stopped working a long time ago. I just purchased an external cd/dvd drive to burn, and i need to know why it won't burn to the dvd. It recognizes the dvd i want to copy, anydvd does its thing, it goes through the copy process, but when i put in a blank dvd to burn it- it does not work. There must be a way to get this to work so please someone tell me what to do?????????????
