For some reason I am getting a error message when dragging certain VIDEO_TS folders into Toast to burn. The error message says "Source VIDEO_TS folder appears to be damaged". The discs were originally ripped with MTR. This only happens every once in a while, but it is getting rather irritating. Anyone have an idea how to make these folders work?? Re-ripping is out of the question since I don't have some of the original disc with me at the moment. Any help is appreciated. Thanks!
