For no apparent reason, a couple of days ago a problem started with accessing the iTunes Store. It's incredibly slow. Just to listen to a song clip it says its rebuffering every couple of seconds. Movie clips are pretty much impossible to watch. I have also noticed that trying to stream video on certain sites such as on bbc.co.uk has the same problem (but cnn.com is fine), so perhaps it's a quicktime issue. My internet is DSL and works full speed, so that's not it. I tried removing and reinstalling latest versions of iTunes and Quicktime, but that doesn't fix it. I have a MBP (SR) 2.4ghz with 2gb ram with OSX 10.5.1. Anyone got any ideas what it is or what I could try to fix it? I've seen a few other reports of this problem on other forums, but no solutions. Thanks.
