Problem:

When doing this:

import fl.video.*;

I get this:

1172: Definition fl.video:VideoPlayer could not be found.

Solution:

I dragged an “FLVPlayback” component onto my stage, and then deleted it.  I guess that forced flash to load in the needed classes.  I’m not sure if this is a bug of if I’m missing something.  I found my answer at the Actionscript.org forums, where it looks like a few other people may have had the same problem.  I think there’s some people there that have posted speculations on why this might happen.  If you care to read, the link is below.
