Ok, here is my problem: I was using a dell 4400 running windows xp SP2 and I wanted to watch the WWDC Keynote. When I hit play, it said something about needing a newer version of quicktime (I was running quicktime 6) After downloading and installing quicktime 7, I tried again, and this time, It gave me a message about changing the MIME file associations...or something along those lines. Long story short, I did, and now I have a reverb of all sound coming out of my speakers be it windows beeps, music, videos....anything. Basically what I need to know is how do I fix this? Thanks in advanced for any tips!
