Which version are you using? I was testing the Encore DVD 2.0 Trial, and it allowed me to burn the DVD to FOLDERS on my hard drive. Once on my hard drive, I can burn them to dvd disc as many times as I want (I use IMGBURN to burn from DVD Folders). Check if your version of Encore burns to DVD Folders, or perhaps can create a DVD Image file (*.ISO). This minimizes burn errors because everything is prepared/sorted properly in the Image file.
