In 10.4, an internet audio file now opens with Quicktime?

Question

Many thanks in advance for your attention.
When I was using 10.3 (and before), when clicking on an audio file on the internet, RealPlayer 9 automatically opened.
One could see the % of the file being downloaded and then (quickly), one would automatically hear the audio clip.
Most often, I am talking about audio clips available on NPR (National Public Radio).
Since I have installed 10.4 (now at 10.4.3), when I click on the same audio file, now Quicktime opens instead. And then nothing happens. Quicktime opens, a Quicktime Player is seen, but I hear nothing and nothing tells me whether the audio file is being downloaded, is ready to be listened to, or anything.
With Quicktime 7, is RealPlayer now supposedly superfluous?

Many thanks QuickTimeKirk,
But think I need more step-by-step directions.
1. I have RealPlayer (9) already.
2. MIME settings in QuickTime Preference Pane. Set it to use RealPlayer for the Format .SMIL How?
3. In the QuickTime Preference Pane, there is a box for .SMIL, one box only, under "Miscellaneous." It IS unchecked already. But NPR still opens with QuickTime.
4. By "Change your Mac to use Real Player to open .SMIL files - ." I assume you mean, I will be on NPR, download a QT file and then try to change it to a RealPlayer file under "Get Info?"
