I'm having 3 dvd videos which was converted from .avi to DVD using ConvertXtoDVD tool. After conversion, if i open a video (VIDEO_TS folder), i could see .VOB, .BUP , .MPEG,... files and if open another video (VIDEO_TS folder) i'm seeing same kind of files that too in the same file names. When I add a DVD video for burning (using nero), and then if i try to add another DVD video, it's asking "Whether to replace the files?". This is because of havig the same file names. How can I burn all the 3 DVD videos into a single DVD?
