dude had the same problem here is what you do
1.kill donwload (could not move to library )
if that is what it says
2. go to library go into inclompete files and restart
donwload and usually you will see that for some
reason its only at 50 to 80 % after that it should
finish donwloading and move to library with no problem
trust me try with one movie and youll see
