Hi Shane,
Thanks for the help, I actually thought this might have been the problem as well but the QT file was still a few MB or even GB big and wouldn’t a reference movie only be KB big? Also, when I would try to preview it on the different computers, it would let me preview with the space bar, but it just would never play or open with QuickTime. And when I exported from it, the settings were never changed, and the export did have “Make self contained,” checked.
So I can’t figure out why this would be happening if it wasn’t a reference movie. Any other thoughts??
