There are a lot of complaints on the Apple Discussion Forums about this issue (and no solutions): when streaming music over an Airport Express to my powered speakers (same happened with my stereo) I keep getting 1-2 second drop-outs. I am doing a clean install of 10.4.x, and I'm wondering which was the most stable version in this respect. Or is it iTunes? Or QuickTime? Does anyone else have this issue? It certainly makes listening to streamed music an unpleasant experience.
