Hello, I am trying to back up files on my hard drive. I have a folder of tv shows I have accumulated, and it is approx 30GB. I want to put these files on DVD-R, without having to move them around. I was hoping that Toast would start to burn and just tell me when to put a new DVD-R in but it does not. Is there a way to allow burning sessions in which i only have to change the DVD-R once full. Thanks!
