@ rfc5stars: I might add that the XP CD-burning option is not very popular around here. Once you have installed a dedicated burning program (like Nero or RecordNow), its limited features become somewhat useless. In fact, many users even disable this function, as it can cause conflicts with other burning software. If you are interested in drag-and-drop burning to DVD from within Windows Explorer, you may want to look into the DVD-RAM format (or maybe wait for Windows Vista).
Concerning your RecordNow installation, I hope you didn't install the downloads shown in the first post from that thread I referred to above, because these are almost two years old. If you want to continue using RecordNow, you should look at one of the last posts in that thread (#283) with a link to more up-to-date information.
