I hope you realise that you can indeed use CD-RW media without using packet writing!
You can burn anything (data, Audio CD, VCD, SVCD) onto CD-RW media just like you can with CD-R media, and you can burn multi-session CD-RW discs if you want just like you can with CD-R media.
The only difference is that at any point you want to start from scratch on a CD-RW, you can just use the Erase function of your favorite burning program, and then you have an empty CD-RW once again!
The builtin CD Recording function of Windows XP is perfectly capable of handling this for you if you merely want to burn data CDs. For Audio/Video CDs you need other software.
So there's no need to use your CD-RWs as frisbees! :disagree:
