A projector is a movie intended for play outside of a web browser. A projector can include a
player (called the Standard player), Xtra extensions, multiple casts, and linked media in a single
file. A projector can also include several different movie files. Configured in this way, a
projector can be a completely stand-alone application.
You can use the Shockwave player projector option to make a much smaller projector. A
Shockwave projector uses an installed Shockwave player on the user's system to play a movie
instead of including the player code in the projector itself. If no Shockwave player is installed
on the user's system, the user must download a copy. A Shockwave projector is excellent for
distributing movies on the Internet that you don't want to play in a web browser.
You can also reduce the file size of a projector by turning on projector options that compress
the movie data, the player code, or both. In Windows, compressing the player code reduces the
minimum projector size from approximately 2.1 MB to 1.1 MB for a projector, and to about
60K for a Shockwave projector.
On the Macintosh, compressing the player code reduces the minimum projector size
from approximately 2.5 MB to 1.2 MB for a projector, and to approximately 12K for a
Shockwave projector.

Protected movies (DXR extension) are uncompressed movies that users can't open for editing.
These can be useful when you want to distribute uncompressed movies on a disk, but you don't
want users to edit the source file. Protected movies may play faster than Shockwave movies
from a disk because they do not need to be decompressed. These movies are preferable if disk
space isn't limited. Like Shockwave movies, protected movies do not include the information
necessary to edit the movie or the software that plays the movie. They can be played only by a
projector, a movie in a window, or the Shockwave player.
Note: To edit a movie packaged for distribution, you must edit the source file (DIR) and create a new movie in one of
the distribution formats. Always save your source files.
Using linked media on the Internet
When you distribute a movie on the Internet for playback in a web browser, the linked
media must be at the specified URL when the movie plays. Otherwise, the user will receive
an error message.
Distributing movies on a disk
Whenever a movie plays from a disk, it accesses all external linked files the same way that it did in
the authoring environment. All linked media—bitmaps, sounds, digital videos, and so on—must
be in the same relative location as they were when you created the movie. To make sure you don't
forget any linked media when you distribute a movie on a disk, place linked files in the same
folder as the projector or in a folder inside the Projector folder.
If your movie includes Xtra extensions, you must include the Xtra extensions in the projector. If a
movie distributed on a disk connects to the Internet in any way, be sure to click the Add Network
button in the Movie Xtras dialog box.
Distributing movies on a local network
If you plan to place a movie on a local area network (LAN), all files must be set to read-only, and
users must have read/write access to their system folders. Otherwise, the requirements are the
same as for normal disk-based distribution.
