Yeah some people have definitely been having probs with SP2. There is a quickpatch for it but this patch may not necessarily fix your prob. There's bound to be several more patches out for sp2 (do a search on the forum for sp2 & you'll find a link to the patch - I posted it yesterday.)

Yes you could be right about the mp3's. If MS has anything to do with them then they may well be copyright protected. From what I've heard (& I might be wrong) that at least some of those mp3 sources's you purchase over the net are copyright protected. I don't know how that works.

But then, there may also be bad sources out thre that are offering corrupted files on purpose/not. If you know the source you could block them.
