That's strange. You should have already had read/write access since you're logged in with that account. Did you ever change your user/login name on this account? Sometimes that will cause some of your permissions to get screwed up. If anyone else is reading this: don't ever do that, create a new account.
So you got it working okay?
I think it had to do with my clean install of Snow Leopard and restoring user settings from Time Machine. I've found a few folder permission errors. I did the same thing with my Macbook Pro but I haven't had any of these issues. I might just do a clean install and restore my user settings from the MB Pro.
As far as the scripts working, it is running great. Thanks for all the time you spent to build them. I just need to set up scripts on my iTunes Server to pull the movies over the network and add to iTunes automatically.
