Just two off topic things.
I've been using XP since 2005 and have NEVER seen a blue screen.
Whether the alternative media players are better than WMP when you have all the necessary codecs installed is highly debatable. You can make music sound better with WMP than with any other one I have tried. I have MPC installed but I really only use it when I want to see more information about the file being played, like framerates, bit rates, codecs used, etc. It certainly doesn't play anything any better than WMP 10 or 11 do and the difference in sound quality is very evident.
The color issue is puzzling and as far as I've seen only affects XP Home. I haven't seen a report of the problem by those using XP Pro.
