There are 10 mp4 movies in my Movie Library within Itunes. I've noticed that when I sync with Itunes often I would get a message saying "Can't find "xxx.mp4". I have ignored the message for a while but today I notice that of the 10 movies that are still in the Itunes Movie Library only 3 were on the Ipad. I tried shutting down and starting up again but nope, still only 3 movies on the Ipad. I had 10 a while ago. I ended up deleting the 3 movies, deleting the 10 movies from Itunes, and pasting them back again. I got an error saying it couldn't fine 1 movie but I just deleted it from Itunes and pasted it back in, did a sync and now I have to 10 movies back again. My question: Are other folks experiencing similar behavior? Anybody know what might cause such odd behavior? Is there some kind of a fix for this? Otherwise the Ipad appears to function normally as far as I know.
