Mac-using readers may well already know of Flip4Mac, the free Quicktime components which allow OS X users to playback Windows Media files within Quicktime. For Windows users, that may seem a bit unusual, but given that Microsoft no-longer develops Windows Media Player for Mac and actively points to the Flip4Mac site, the Telestream components are certainly welcome for those requiring access to Windows Media content on Mac OS X.

Since Mac OS X 10.5 Leopard's launch in October, users have been left without Windows Media support, however that absence is no more, for Flip4Mac is now Leopard compatible. Not only that, but the developers have also announced that the paid-for tools and plugins which allow the exporting of Windows Media content on OS X now also offer 'Export to Silverlight' options. If you're unfamiliar with Silverlight, it's Microsoft's answer to Adobe's dominant Flash format for online interactivity and media.

If you own the Flip4Mac tools already this update is, like the playback components, free and available from the Flip4Mac site.
