I cannot download movies. Download starts but times out. Error message is as follows: 30 MB of 1.3GB stopped (err-8008 sometimes get err-3259). I've tried two movies with the same result. However, I go to my son's computer and have no problem. I can download music with no problems. I have un-stalled and re-installed iTunes per Apple request with no change. Virus Detection and Firewalls are disabled. Running XP SP2. Help!
