I've been trying to backup Gladiator over the past few days and keep running into the same problem.
I run it through DVDDecrypter and DVD2One and have the files placed in a VIDEO_TS file as usual. I open my burning program (RecordNow Max) and choose the video folder as the one to burn to DVD. When I do this it tells me that the file is too large and cancels the burn.
I looked in the folder and the 5 video viles appear to be the same size as always for a large movie. There are 4 other files there and tehy appear to only be a few KB larger than usual.
