How do I deselect iTunes as a default app?

[stopbush]

A friend of mine is sending me Real video files. Whenever I click to open them, iTunes starts up, but it won't recognize the files to import them. I end up launching Real Player and using the open function. I can't see where I would deselect iTunes as the default and set Real Plater as the default for such files.

Help!

1. Think you can do it this way

Select (but not open) the file. From the Finder, select "Get Info". You should see the "open with" option, and a button to allow you to change all files of that type to open with the selected application.
