The_Man,
For WMV files to play in the browser, I use Flip4Mac WMV Player ( http://flip4mac.com/wmv.htm ). Basically, it adds a plug in to Quicktime Player that allows you to play WMP in Quicktime. It costs $10 to buy, but there's a free trial (be warned, though, that the free trial will only play the first half of movies). Honestly, it was worth the $10 because it's so much simpler than Microsoft's version of WMP for Mac. I've tried VLC, but it was a bit confusing and wasn't good for browser plug-ins.
