I'm happily browsing the internet with firefox/safari and I decide to open up iTunes in order to play some music and it starts to download video podcasts. No problem right? I like to watch video podcasts... except suddenly, the pages I try to load in firefox start to hang. It is like they all start to time out. Until I pause the iTunes downloads, then everything starts to work properly again. It is not only iTunes that hogs the pipe, I also have this problem everytime time machine makes a backup. Does anybody else experience this? Anyone know how to fix it? I don't remember having this problem back when I was a windows user. I might just need a fresh OS/X install...
