I backed up my iTunes library to disc because I am about to transfer the library from my PC to my soon-to-arrive Mac Pro. It took 4 DVDs, as expected, and all went to plan. The ONLY thing I was wondering about was whether or not the album artwork transfers with the files/folders on the disc? The majority of the artwork was assigned to the songs by hand, so do you know if they will transfer if I do it this way or will they need to be added again? Any other tips for backing up the library this way? I'm not likely going to have the PC and Mac Pro setup as a network so this seemed to be the best way to do it.
