I only have 3 .vob files! I don't have any .ifo! I originally had .avi file and my software converted it into .vob. So, how should I make them Run on my DVD player!
You need a complete DVD structure to burn a working DVD Video disc. If you are missing some files, you should convert your VOB to MPEG-2 using, for example, Rejig, and then re-author a DVD using, for example, DVDStyler.
