I had used a good open source solution called Textpattern. I was in the same situation as you, except instead of different parts of media, we used different topics. Just to give you an example our blog site was aimed at the exact thing a regular newspaper was aimed at - multiple editors, multiple journalists, and overall just multiple contributors.
Textpattern has very well thought out permission based settings. I would say Wordpress is much like a one user computer as where Textpattern is like a Linux server. It allows a better control of design as you can pull up code from the admin panel (CSS, conf files, etc.).
The parent site textpattern.com is where you can consume more information on it. There is also a sibling site textpattern.org where most of the community action happens (plug ins, themes, etc.).

So here's my situation:
What I want to do is take a group of individuals (friends), and have a blog/website where we all contribute to certain areas of things. I.E. One person does news, one does movies, another music.
In the past I've used LiveJournal (definitely individual orientated) and Blogger (had a group experience here, it was too rigid).
Things I'm looking for in it are:
The ability to control the HTML/PHP/SQL elements of the page.
Multiple User access, with varying levels of controls
Ideally I'd like to not have to pay, but payment could be an option for an appropriate solution.
Recently I've been looking at Wordpress, but I'm not sure about it, especially after reading the WordpressMU site.
Any suggestions on what the best solution would be?
