I've been running xp forever and I bought mohaa on day one I've NEVER have any probs running 1.0 or 1.1 from xp (2600 build). It's not the os I promise you that. It's most likely your "burned copy" that's screwy. I used clone cd and it installs fine, just dl the nocd from here and you should be fine. and since you "should have the original if you have a burned copy, that shouldn't be a problem right?...right???
