Ever since I upgraded to Itunes 9.0.2 I cannot tag handbrake m4v video files with new artwork. Is anyone else having this same problem? If I try to drag artwork from safari to the artwork tab it doesn't do anything. If I drag the artwork to my desktop first, then into the artwork tab, it drops the artwork like normal but after I hit OK the the file's artwork reverts to the screen shot from the beginning of the file. If I then go back into the file info the artwork is gone. It's as if Itunes is rejecting the artwork. I have tried this with several different video files and several different pieces of artwork and nothing helps. Any ideas?
