This may not be a solution as some people are weary of codec packs. I
use this one on my XP & Vista boot and I am happy with it.

For the most part I hate the intrusion and quirkiness of WMP and this
codec pack comes in with a Zoom player that will play everything you
want to throw at it, aside from giving you the necesary codecs.
