If you select All Tracks, all the tracks with the same language would be selection, (In â€œDVD to Mobileâ€, Only the first track will be selected, because now this feature not support multiple audio tracks output )
If you select DTS, the DTS track will be selected, other track with the same language will not be selected.
If one of your DVD unlucky not any tracks meet your selection criteria, you can decide DVDFab how to do.
