When sharing project to iTunes I get an error message "missing media"

Mac Book Pro OS10.9.5  Imovie 10.0.5  Storing library on external hard drive.  Only opening iMovie from the library in the hard drive.  Working fine other than problem below
Have a project that I tried to share to iTunes and it states there is missing media and if I continue that media will not be included.  How can I find out what is missing? 
I see a Yellow error triangle symbol in the heading of the title, but is is not a link to anything and does not direct me to anything and I don't see that symbol anywhere else.  Project appears to play just fine.  When I exported to iTunes - the intro of my video is missing.  Which would be logical to think that is the missing media - however, I shared another project at the same time that did not give me the error and did not have the yellow triangle symbol and it too is missing the intro?? 
I did copy the intro from the problem free project and pasted it into the project with the problem above.  I also copied an pasted a few other sections the same way and those sections are not missing in the iTunes export.
I exported to file and saved to jump drive and opened from there - no problems - all parts there.
Maddening.  Anyone have a fix for this.  Help appreciated.  Thanks

I seem to recall that this may be cause by overloading the USB bus (lack of power to go around).  Shut down your computer.  Reset the iPod shuffle using this procedure.

Disconnect ALL peripheral USB devices, including keyboard and mouse.  Power up the computer.  If you need your mouse, connect it and launch iTunes.  Connect the iPod shuffle to a direct USB port and try the sync again.  See if there is any difference.
