X5

Annex: Digital Video and Data Storage 339
DVD-R/+R: This medium may only be written to once. The DVD-R may be specified
with file structures for DVD video, DVD audio, or DVD-ROM.
DVD +RW: +RW drives allow re-writable DVDs to be created which may be read by
almost any commercial DVD-ROM or DVD player. The companies involved are
mainly Philips, Sony, HEWLETT PACKARD (as well as Ricoh, Yamaha and
Mitsubishi).
DVD-RW: This is a write/erase DVD technology promoted by Pioneer and Sharp.
This format was developed by the Pioneer company and should be compatible with
existing DVD players.
DVD-RAM: DVD-RAM technology is based on either Phase Change, MOs, or hard
disks, etc. and is now almost 100% incompatible with all available players.
Due to the small storage capacity and incompatibility with DVD players, setting on
this standard is not recommended.
Note: MAGIX Video Pro X5 supports DVD±R and DVD±RW, but not DVD-RAM.
Blank discs: Single-sided recordable blank discs featuring a capacity of 4.7 GB and a
duration of approx. 2 hours.
Copy Protection
Macrovision (APS): The movie industry claims that even DVD-ROM drives and
decoders or diagram cards with composite outputs or s-video outputs must support
the Macrovision analog copy protection (APS). Only some older DVD players do not
possess APS.
APS adds additional signals to a DVD’s stored graphical data. The data is almost
unchanged. These supplementary signals disturb the synchronization and the
automatic recording regulation of most video recorders to prevent recording of the
video. They are not noticeable on the television or the monitor, however.
Content Scrambling System (CSS): CSS prevents saving and duplication of DVD
video tracks to hard disk. The VOB streams of DVDs without CSS can otherwise (like
other video files) be loaded via the Import Video button
There are further types of copy protection besides APS and CSS which ensure that
retail DVDs cannot be copied without distortion
