Sample .ram file contents

Pointers to content encoded for Real Player do not require AUTHOR and COPYRIGHT, but uses port 554:
rtsp://real.playstream.com:554/iberlin/video/dance.rm

Notice from the above:

• different protocols are used: mms and rtsp.
• the .asx pointer files need to be in the same directory as the HTML page which call them.
• To edit these files, first change their file extension to .txt

To display video, provide an OBJECT section for Microsoft browsers and an EMBED section is for Netscape browsers:
