Why wont my videos upload??!

Hello!!! So as most of you saw I posted this video prior to/on the 4th of july...problem is I uploaded two more and they wont show!!




I had uploaded an outfit of the day and a dramatic eye tutorial- superfun!! For some reason, no matter how many times I try to re-upload, youtube accepts the video, and it never shows up! Not even in processing :( I use iMovie and upload directly to youtube on a Snow Leopard OSX... anyone have ideas as to why this is happening?? Urghhh!!
