.. User Advice on MPEG-II Decoders
All DVD-Video material is compressed using MPEG-II compression. DVD-Video, with full-motion video and multi-channel
sound (multi-lingual soundtracks, surround sound, etc.), is a data-hungry application. Without compression, you would only
be able to fit a 5-minute movie onto a 4.5GB disc (the DV format is equivalent to 13GB per hour). MPEG-II compression
allows you to fit a full-length feature film, plus bonus material, on just one disc.
In order to play DVD-Video discs using your LaCie Slim DVD±RW Drive, you have to use DVD
Player supplied by Apple with Mac OS X.
If you would like to create your own MPEG-II files please refer to the Toast 7 Titanium
documentation.
.. File System Formats - Definitions
When writing DVD±R/RW and CD-R/RW discs, you will have the option to assign the disc a particular file format (the way
in which a computer names and organizes files for storage and retrieval). There are essentially three file system formats to
be concerned with when using a LaCie DVD or CD Drive:
• Universal Disk Format (UDF)
• ISO 9660
• Mac OS Extended
UDF - This file system was developed to ensure consistency between various optical media, compatibility across platforms
and among various CD and DVD applications. UDF is used by DVD to contain MPEG audio and video streams, and is
required by DVD-ROMs.
ISo 9660 - This is the standard file system for CD-ROMs, which allows them to be read on a Mac, PC or other major
computer platform. Microsoft created an extension to the format, called Joliet, which allows for Unicode file character names
and file names up to 64 characters in length (twice as many as the ISO 9660 Level 2 and 3 specifications).
Mac oS Extended - Also known as HFS+, this is the file system used by Mac OS 8.1 and higher. If you will be using your
disc only on Macs, this is the preferred file format.
