Ripped DVDs and the empty AUDIO_TS folder
A reader who wishes to remain anonymous is curious about the structure of DVDs. He or she writes:
A friend has a DVD that he needs to turn into a QuickTime movie. He’s used a program that copies the contents of the DVD to a folder on his Mac. Inside this folder are VIDEO_TS and AUDIO_TS folders. The audio folder is empty, though. Does that mean that the converted movie won’t have audio?
No, it doesn’t. The original DVD standard didn’t include an AUDIO_TS folder. All content was intended to be found within the VIDEO_TS folder. (In case you’re curious, the TS stands for title set.) This includes video as well as the audio that accompanies that video.
The AUDIO_TS folder was added as an option after the standard was established. This folder was created for standalone audio files much like the audio tracks on a CD. The idea was that DVDs would replace CDs as audio media. It never caught on but the folder remains, even though it's invariably empty.To read this article in full or to leave a comment, please click here
