Window xp OEM install problem

I am having trouble loading window XP pro OEM sp2 using Bootcamp on my macbook OSX 10.5.8 It gets through copying all the files and reboots successfully through to the install window and the setup program for windows (where it displays various marketing info and has dot buttons down the left hand side). It says it will take 39 mins to setup but the counter never changes and I have left it up to an hour and nothing happens although once I did get a disk error message (something about cleaning the CD - can't remember exactly). I am doing full installs and have tried FAT and NTFS. At first I thought it was because it was an OEM but it is a Microsoft OEM and other people online seem to have no problems installing and if there is a problem it seems to stall well before the setup window. Is this a dud CD or version of windows or am I just doing something wrong?
