My file with the video files I want to burn don’t have the file VIDEO_TS.IFO, I’ve searched google for the file, but no help. I’m using CloneDVD2, so what do I do to avoid this message and make a dvd?
You could create the file with IfoEdit.
Easiest way is to make another backup from the original. Any VIDEO_TS file you might find using Google is not guaranteed to work.
