In order to play .wmv files, you need to download and install Flip4Mac. The latest version of VLC will also play them. The Quicktime codec Perian will handle .divx as will VLC. Virtually everything plays .mpg out-of-the-box.I'm looking for a good media player for mac osx 10.4.8 that can play .wmv, .divx, .mpg, and pretty much everything else. is there a good one out there?
