Can not change password for podcast with password

I have a podcast that uses a password that I saved. Now the password has changed and I cannot find any way to change the password.

I tried removing the feed, then adding it again, but it appears to have cached it because it just brings up the feed without prompting for the username/password.

The only thing I can think of is creating a whole new iTunes library, obviously that's unacceptable!

Please help!

Thanks,
