Thanks for the replies, I've got both the news version of VLC and WMP The files on my iBook have the ".wmv" extension I do not have a windows pc with me right now, so... I've just try few minutes ago to read them with MplayerOSX 2 and surprise, I can read some of them but not all of them, I have the audio but not the video and the "window media" icon is jumping on the dock !! Regards,
