When i was using internet explorer 5, i'd click on the speaker icon (for the mp3's on this site) and the mp3's would open in a new window (streaming) and start playing with quicktime. I upgraded to net exlorer 6 and dont know how to make them playback like that again. Which settings do i have to change?
Try going into Tools -> Internet Options-> Advanced and see what it has for the multimedia section. You might need to check the play sounds option or something...
That's because Windows Multi Media player took over your file association for MP3's. If you go into Quicktime (or whatever your prefered player is) and look under options there will be a setting for File Associations. Dig around a little and you will find it, then you want to tell it to be your default player for MP3's.
