I made more than 3 hours of movies + pictures with my camera. Used Movie Maker to arrange them together in 6 wmv files with titles and transitions. Then I used Nero 7 Essentials to burn them on a DVD +R DL, the software coded the movies to NTSC. The DVD plays wonderful on my DVD Player connected to the TV. Now, I want to duplicate it to mail it to family and friends. Nero 7 Essentials not want to duplicate DVD +R DL to another DVD +R DL, it wants me to buy DVD -R DL and I not want to do this. Is there any freeware that I can use to copy DVD +R DL to DVD +R DL ?
