1) if your Xp cd comes as "SP1", you'll need SP2.exe to include it in your DVD 2) if you want "post SP2" updates to be included too, you need an update pack like RyanVM's 3) if you want other programs to be included, you can use those addons you found on this site. You don't just add the program on the disk, the addon makes the program included in XP when installatiuon is finished. 4) you include SP2 in "Service Pack", post SP2 updates and addons in the "Hotfixes, addons" part of nLite. If the programs you want to include are not to be found as addons yet, you can make your own, there are explanations about how to in the ddon forum. I hope I answered all your questions. If not, someone else will finish.
