The CNN live video can work with mplayerplug-in, But requres a few things.
1. User agent switcher and a mac string.
2. Recompile mplayerplug-in/Source/plugin-setup.cpp file.
Add Flip4Mac to the line stating "Windows Media Player plugin"
and Change the quicktime line to "QuickTime Plug-in 7.2"
3.To test enable the Mac string and go to cnn live video.
