It often happens so that the source DVD contains more than one language. It is very useful when you can speak these languages or learn them. But if you do not need them, they can be easily removed. Moreover, if you compress the source DVD to fit the target disc, removing the unneeded languages can help avoid stronger compression of the video, thus enhancing the quality of the output video.

When the disc or a hard disk drive folder is opened, all the available languages for this DVD video can be found in the Languages window. You can either check all of them or uncheck the languages you consider unnecessary.

Note: there can be not only other languages but also audio variants of one language that differ in the number of channels and audio codec used to record them. It is usually done so that the DVD could be better played on different hardware or software players. If you are sure, what track is best played by your DVD player, you can leave only this track on the target DVD and uncheck all the other audio tracks.
