Help please to burn multi discs

[]-[êll.Ôñ.ËÀR'][']-[.]

I got a unattended version of black xp with all the frills & bells and want to burn to DVD for installation on another pc at a later date the problem i have is that the iso file is 7.41 gig so wont burn on to one DVD alone (due to lack of space being 4.7 max)..... would appreciate if anyone could advise how to burn to two DVDs so it will boot up and load.
tried magic iso but on new ground there so any help would be most appreciated.
