As an alternative to reloading the discs into the DR-1, it is possible to increase the space allocated on the
hard drive of any XD20 so that it will hold more film content. The necessary increase in space would
depend upon the rate of loading new titles and the number of weeks of play on a given screen. See -
Film
Reserved
, under the Disc Space section on page 106, for specifics on increasing allocated space for film
content.
2.4. Managing Disk Space
The XD20 250 gigabyte hard disk reserves 25 gigabytes of space by default for film soundtrack and CSS
content. (See
Disc Space
in section 7.9 for information on changing the amount of reserved space.) XD20
uses about one G-byte of space for an average two-hour feature with soundtrack including DTS Access™
content, such as subtitles. Alternatively, one G-byte can also hold content for approximately 50 three-
minute trailers.
XD20 automatically ensures there is enough storage space on the hard drive before loading new feature
and trailer soundtracks. When necessary, it deletes old material to make room for new content. Old
material consists of the features and trailers that have not been played for the longest duration of time. All
content associated with the selected feature or trailer, such as different language versions, is deleted at the
same time.
Content for features or trailers can be deleted manually as well. See
Delete Contents
on page 37
for more
information.
For XD20 units with the Video Option, the hard disk space for the video content is separate from the
space for the film content. Adding video content does not reduce the space for film content, and vice
versa.
