If you are considering new software, maybe you should consider an alternative to Nero. Personally I use Roxio. You will find negative comments on the internet about both, but my bad experience was with Nero. My old HP 450 PIII came with a burner that had Adaptec (now Roxio) software that did packet writing to CD-R. When I upgraded from Win98SE to W2KPro it no longer worked. I ended up buying Nero 6 after carefully reading the info on the outside of the box, and even explaining to the "knowledgeable" sales person at Compusa what I wanted to do with it. It was only after I took it home and opened the box and reading the manual inside, that I found out it did not support packet writing to cd-r. I did a long email battle with their tech support and customer service, had to threaten them with filing a complaint through comsumer protection in CA where their US office is located. I finally got a RMA and sent it back, and received a full refund. In the meantime, I found Roxio 5 Basic OEM for around $8.00 and use it for packet writing to cd-r, buring cd's, copying cd's etc. I bought dual layer dvd/r/rw drive for my other computer and it came with Roxio 7 basic, it works well too. I will never forget being told by Nero tech support person "we do not issue RMA on opened software" when it was not possible to find out it would not support packet writing to cd-r until you open the box and read the manual! They even told me in one email "Nero does not support packet writing to cd-r, read the manual". Whew, I decided never buy Nero anything. I have bought several drives that came with Nero OEM, never even tried to use it. I just use Roxio because it works for me, and that is what matters.
Whether you get Nero, Roxio, Sonic or what ever, all that matters is that it works for you and does what you want it to. Good luck.
