Okay I had all my music on my PC desktop for about a year and half now. My 5g Video iPOD was formated for a windows machine. I just bought a MacBook Pro and copied all my music to my MacBook Pro and formated it for Macintosh. Which included the restore the factory defaults. Every time I plug it in a nice friendly message pops up and says iTunes cannot copy my videos because my ipod cant play them... if i just click okay it tries to synch up the computer with music etc. Then about 1/4 into the way i get "The iPOD "araBRUNO" cannot be updated. An unkown error occurred (-50). I don't know, if it was a PC problem I could just hit something hard enough and it usually fixed the problem, but as far as going into the Mac crap of everything I am baffled and amazed at all the new guey interfaces and "help" hints.. Please tell me what an idiot I am and tell me how to fix it.
