I was wrong earlier about what programs I've set it to run through. I've tried Windows Media Player and VLC Media Player (these computers don't have Quicktime). The IT guy thinks it's a file-size issue, but I think the problem occurs too randomly for that to be the case.

I can't try the "Use Enhanced Video" option because it's grayed out and un-selectable in the toolbar.
