I only have one video project that I ever published to iDisk. It didn't have any music or photo files attatched to it, just a few clips stitched together. I can play these clips right now in the Event Library (so I know the source files are on my computer), but strangely, under the Project Library, the project is not there. I'm almost certain that I didn't store the project on iDisk; I just completed the video and published it to iDisk (as a .mov file I think) for family to see. I've tried to figure out how to get iDisk to stop looking for this project to no avail.
I don't know if others have experienced this, but if I click on any project and on the menu bar select Share --> Remove From --> Media Browser... it lists iPod, iPhone, iPad, tv, Computer and MobileMe. Why would MobileMe be an option here? This is the case for any video project I select. Didn't iLife '11 and/or OSX 10.8 remove all mention of MobileMe? I wonder if this is part of the problem too.
Edit: I just removed every project I have from the Media Browser. Still no luck.
