ilja... if the firmware updates don't work out, or if cleaning out the drive as MACy suggests doesn't help, here's a couple other things to try:
If you can get online, run Windows Update and install all the updates available. Perhaps there's one that addresses this issue. If that fails, then try deleting the drive from the Device Manager and let Windows re-add it. Hopefully this time it will install the correct drivers.
What part of the problem "may" be is simply Windows XP, being a 7-year-old OS now, may be having trouble recognizing or properly utilizing the latest hardware, assuming you have a relatively new Mac. Sure... Boot Camp should have the drivers it needs, but if Windows can't read the DVD because it doesn't support that drive fully with a fresh install, well loads of good that does!
If the above tips don't work, I have one more idea but I need to try it at home first to be sure you can do what I'm thinking of.
