I also have been an internet user for over 10 years and have never heard a bad thing against Quick Time,often against Real player and Media Player. I have used Quick Time for over 5 years ,with no problems. I have also asked a few friends and they also have never heard of this complaint. Where did the complaint come from?
Macaonasa....don't worry about having Quicktime,as Bremner says it's worth having. Just download itunes..it's great. By the way I have WMp, Realplayer and Musicmatch as well. They are all worth having.
