When a disc is inserted into a DVD player, the player’s firmware is programmed to search for two data folders. The first is labeled “VIDEO_TS.” The second is labeled “AUDIO_TS.” For a disc containing a movie to play in a standard DVD player, the “VIDEO_TS” folder must be present. In some players, the “AUDIO_TS” folder must also be present or the player will not recognize the disc as valid media. Writer Bio
