To listen to and/or watch audio and video files you will need a piece of software called the RealOne Player.
The free version of the RealOne Player is quite sufficient to play audio and video. If you don't already have this software, you can download it from the RealNetworks site (http://www.real.com), there are several mirror sites hosting the software, so be sure to pick the one nearest you.
Once you have downloaded the player, click on the file to set up the software on your computer. The setup should only take a minute or two.
The RealOne Player is available for PC and Macintosh. Along with the software, your computer will need to have certain minimum specifications in order to play the audio & video successfully. 486 DX-66MHz or higher 28.8kbps modem (or network connection), Soundcard & speakers.
If you are using the net at work, you may be on a corporate network or behind a firewall. In this case you should contact your system administrator to check whether RealAudio streaming is permitted by your system.
For a more comprehensive RealAudio troubleshooting guide, see the Real Networks help page.
Recently RTE media files have changed from the .RAM or .RA format to
the .SMIL format.
SMIL is supported by the RealOne media player, among others.
To get RealOne to automatically play .SMIL files, open the player, go to Tools --> Preferences. A window should open up with a menu system on the laft hand side. Select Content --> Media Types and a list of file types will appear. Press the 'Select All' button and then OK.
After this, RealOne Player will be your default player for .SMIL files.
