I have a handful of .MP4 Quicktime files that imported just fine into iTunes in Snow Leopard. I clean installed Lion last night and manually added my files back one by one from my Time Capsule. When trying to drag and drop my movies into iTunes, some would import and some wouldn't. These files weren't purchased on iTunes...just ripped HD movie files in .MP4 format. Again, all of these files were in my Snow Leopard version of iTunes. Any idea why they won't import to iTunes in Lion? They play just fine in Quicktime X.
