This just started a few days ago. Now when I try to add new video files from my camera (imported to iPhoto) by either dragging to iTunes or by "Add to library" menu item, the videos do indeed get copied to the iTunes library (I can see them by browsing) but they do not show up in iTunes as far as I can see in any category. This happened right after I ran out of space on the external disk that holds my iTunes library when iTunes gave me a warning that the disk was almost full and it would copy what it could. I have since cleaned up enough space but iTunes will not show my imported files. Has anybody else seen this issue and know how to fix it? Can I rebuild the library?
