I have all the files needed to burn a DVD movie(Chronicles of Narnia) to a DVD but it contains multiple disks because all the files are to large for 1 disk. I have a bunch of .vob, .bup, and. ifo files but don't know where to split them for each disk. I already have NERO and know how to burn it but am having trouble what's DVD1, DVD2, etc. I have taken a picture of the files.
