Blinking FLVPlayBack Component when loaded from another

I'm having an issue with flv files playing in a loaded movie clip.  I have a 
main swf that is just a loader for the other clips.  The app first loads an 
index clip and then loads a presentation depending upon what selection the user

made.  The presentation is a video with corresponding slides synced using cue 
points.  I am dynamically loading in the cue points from xml and the slides are

pngs.  The videos for the presentations are in videos/ and the xml is in xml/. 

The presentations work fine when playing the swf directly or playing their 
published projector files, but I get the blinking flv icon and no slides when 
the presentations are loaded by my main application.  All the paths are 
relative.  CS3, AS3.

 I'm comfortable with other languages, but somewhat of a Flash/AS noob.  Any 
input is appreciated.  Thanks.

Remember, when loading content into  a SWF, the relative paths are from the 
loading SWF, not from the loaded SWF.  So, if the loading SWF and the content 
it is loading are in separate places, then the relative links are broken.  I 
typically use absolute paths to definitively know that I am loading from the 
correct location.
