I did a search and came up empty for an answer to my dilemma. Okay, I filled my iMac's HD to capacity tonite, causing a ton of problems with my apps. (but that's another story) Before all this happened, I was importing videos into iTunes constantly with no problems at all. During all this mayhem earlier, I kept getting messages saying "Cannot add to iTunes library free up space on startup disk." I have like 11GB free on my iMac HD now and when I attempt to import a video the same way I always have, it does NOT APPEAR in iTunes!! I go to add to library, and before it appeared right away, but now NOTHING, and It's in the right format, I use Handbrake and iSquint to encode to MPEG4. Anybody have any ideas??
