I'm posting this to save others the frustration I've been experiencing in the past 24 hours. One of the key attractors of GTD Connect for me has been the ability to obtain podcasts of specialised content. Imagine my dismay when I tried downloading with iTunes and everything timed out. Again, and again, and again.
The culprit has been nailed down to Norton's Internet Security 2005. For some reason, likely the way the GTD Connect podcast has been protected, NIS doesn't play nicely with iTunes. It's either blocking the downloads or taking so long that they time out. Both programs are fully updated.
The solution has been to disable NIS for the period I'm downloading podcasts. On another PC without a firewall it worked perfectly first go.
So if you have trouble downloading podcasts and assuming you've got the password correct, then it may be your firewall getting in the way.
