Thanks for asking the question i've been wondering about this myself. I've been saving everything to flash cards at the moment. I went ahead and did a filter search on download.com here are the options I found.
Nero 7 works. You just need a valid lisense, then you can get a link from Nero itself. Not sure if your talking about data DVDs or the good kind, but just incase its data i thought i'd offer.
Nah, at work we are putting 7 on the new vista machines. All you need to do is get the working program from nero's website. I do have it on my flash, but i don't think i'm able to send people exe's through email. Gmail blocks it.
