Hey Tconduce, it’s just one of these forum conventions to try and keep everything on one subject in the same thread, it’s cleaner that way. No harm done.
As far as the burning software suggestions you received, I want to warn you against installing and testing all of them on your PC. The number one enemy of Windows is third party software, so you have to try and keep the number of installed programs to a strict minimum, that’s if you want to enjoy your new XP installation for a long time anyway. The best way to slow down and possibly break your Windows installation is to go and test different programs on it. Even uninstalling them will leave enough traces to affect performance (and I can imagine your old hardware isn’t the fastest to begin with).
Bottom line: do your research on the net (there’s screenshots and guides abound for all of them) and choose carefully. I’ll stick with my recommendation for Ashampoo Burning Studio, which, from what I’ve seen, is about as user-friendly as it gets.
