Add audio or video files from the Internet

You can add audio and video files as enclosures from the Internet.

Before adding enclosures, you can set the default media player to Windows Media Player (Windows only) or QuickTime (Windows or Mac OS).

When your default media player is Windows Media Player, you must play the audio and video files in Windows Media Player, and then add the files as enclosures in your blog entry draft.

Note: You cannot insert audio or video files as enclosures without playing them first in Windows Media Player.
