A problem I have been having lately when backing up DVDs is when I take the finished backup DVD and put it in my DVD player it starts to play the disk and then stop, like someone hit the stop button and it just sits there. It never plays on my player. I am using the Ripit4Me-Shrink--ImgBurn process of backing up DVDs. I have had some success using this method but lately it seems more often then not, it comes out not playing. All my software is up to date. Any ideas??
