Improving Media Playback
------------------------

On some machines, particularly those with minimal
RAM, external digital video file playback choppy,
even when running directly off the hard drive, yet
they run fine using MediaPlayer directly.

The problem may be that Authorware is trying to do
too many things in the background while playing the
media. There is an undocumented variable called
"MaxBackground" that you can use to set the maximum
number of background tasks that Authorware is to
tend to. 

Try entering the following in a calc icon:

MaxBackground := 0

This tells Authorware to ignore everything else while
the movie plays.
