A VIDEO_TS folder is obtained when you have copied or ripped data off a DVD.
Place the VIDEO_TS folder on your desktop.
Launch Terminal from your Applications:Utilities folder.
Enter the following command into the Terminal window.
hdiutil makehybrid -udf-volume-name DVDNAME -o ~/Desktop/filename.iso ~/Desktop
Replace 'DVDNAME' with the name you want to want to assign to the disc. Replace 'filename.iso' with a name for a disc image generated by the command.
