Hi there I encountered the same issue after installing my slipstreamed XPSP2. After you install Windows XP the link MediaPlayer on your right click the taskbar DOESNOT EXIST. So run WMP. Being the first time you run it it will tell you to check some settings, file associations, etc. Customize it at your wish. Then minimize the WMP. Being the first time you minimize it, it will ask if you want to ENABLE the MediaPlayer Bar. Click YES. Finally that bar will appear on your right click on taskbar. That's all ... PS: I don't know how can this be done unattended or turned on by default.
