MobileMe: Sometimes unable to select .mov files to upload to Gallery album

When you attempt to upload a .mov file in to a Gallery album in me.com, you may notice that in some albums this works, and in others the option to select .mov files is not available. Note: It is possible that the .mov files will not be available when you try to add a .mov file to an album published using the Aperture application. Aperture does not work with video files.
