I have installed QT on Mac and found it to be very nice (am listening to <a href="http://www.macroradio.net/dyn/MRN/quicktime">streaming radio</a> as i write this)
But, I have also downloaded and installed QT4 on a Windows machine. QT3 worked very nicely but 4 has sound that is totally choppy and very unlistenable. The sound is terrible in both WAV and MP3. Anybody else out there go both ways and experience similar?
