When you
browse through the contents of a DVD you will see the following
folders and files::
| |
| VIDEO_TS |
VIDEO_TS.IFO and VIDEO_TS.BUP |
|
|
VTS_XX_Y.IFO and VTS_XX_Y.BUP |
| |
VTS_XX_Y.VOB |
|
AUDIO_TS |
Folder
originally intended for audio dated but hardly ever used. |
|
|
The .IFO files contain the
navigational instructions and the .BUP files are
actually backup files containing exactly the same data as
the .IFO files.
The Video and Audio streams are
in the .VOB files. You can actually play the contents of the .VOB
files by opening them in a player like the Windows Media Player (if
you do have an MPEG-2 encoder installed).
A DVD can also contain other files
and folders for any kind of data, so you can actually make a
DVD-Video and use it at the same time for data storage. On
pre-recorded DVD's such files are usually intended for playback on a
PC (special programs or games). |
