Why do you use QuickTime for audio and video instead of Real Player?

Apple's QuickTime architecture robustly supports the greatest number of file formats across both platforms, and allows us to integrate playback of such media directly in HyperRESEARCH so you can code multimedia sources as easily as you can with text files.

If you don't already have QuickTime installed you can download it for free from http://www.apple.com/quicktime/
