In the past couple of weeks downloading podcasts on itunes has slowed to point where its impossible. My broadband speed is fine (4-5mbs) and have checked it on multiple occasions and also phoned my supplier O2, but all is as it should be. All other browsers/aps etc work just fine. I emailed Apple but got no help. I have checked Norton settings etc but I have not changed any of these for many months and have been happily using itunes for years. I have the latest version of itunes and have downloaded it again and reinstalled it but still the problem remains. I use Vista and again have not had a problem with it for over 3 years. Does anyone have any idea as to how to fix it? I have a long daily train journey to work and have come to rely on my podcasts to get me through it. Thanks
