I find packet writing in XP to be perfectly satisfactory and very reliable. I use TDK discs. The only disadvantage (which doesn't bother me but might be a problem for others) is that you cannot selectively delete certain files or folders from an XP-written CD-RW. I think other programs probably can do that, but I have never had any reason to use anything but the built-in XP CD writing wizard. You can still write multiple seesions without losing existing data.
