Windows Media players

[Claude Jones]

I'm looking for suggestions on media players. I've installed Real and 
Helix successfully, but haven't been able to get Windows Media to work. 
I've tried mplayer, but I don't think I got all the installation steps 
correct. It seems a lot more difficult to get working than Real was, so 
before investing more time in the effort, I was wondering if this is the 
best (if not only) Windows Media plugin that works with Mozilla?
