Yes. I have no problems with MP3's.
This sounds like a pretty good analysis to me... apart from the fact that I
get dropouts when I have
virtually no load on my WinXP box at all.
I've tried changing my windows settings to give services running in the
background priority over programs but if changing
this setting made any difference at all it made the problem worse.

I'm quite desperate for a solution to this.
Until it's fixed (one way or another), I'm back to CDs... :-(
