I want my wife to use Linux but she likes only how Windows Media Player 9 looks (not 10 or 11). Does anybody knows about good looking WMP9-like skin for mplayer?
Any reason it has to be mplayer? Since I think it will be easier to find a good skin for VLC (more widely supported).
HowToGeek wrote a nice tutorial on how to do so, however his example is Windows Media Player 11
Perhaps you should check out his link to the official VLC skin page.
Or you could just install Windows Media Player 9 under Linux with Wine.
