Remarks

This element specifies a URL for a piece of media content. The URL can point to any media type supported, using any protocol supported by the Windows Media Player. The most common use of this element is for URL rollover. If the Windows Media Player is unable to open a piece of media defined in a REF element, it tries the URL in the next REF element. Once the Windows Media Player opens media content from a URL defined within the scope of one ENTRY element, it ignores subsequent REF tags within that ENTRY element. After the piece of content is done playing, the Windows Media Player moves on to the next ENTRY element, if any.

Important: Once the Windows Media Player establishes a connection to a referenced piece of content, it ignores all other REF elements in that ENTRY, whether the connection terminates normally or abnormally.

To use compact disc audio with your CD-ROM drive as input to the Windows Media Player control, specify cdaudio: (with the trailing ":") as the HREF value. For more information, see Compact Disc Audio Playback.
