What ap and version are you using to burn the disks and have you looked to see if there are issues addressed on the burning software's site.
There have been updates from Nero and Roxio that address such issues with SP2 and SP2 is a critical update that patches numerous exploits found existing before it. It is primarily a security update although it adds additional functionality to XP as well.
Primarily for Nick :
Operating without SP2 not only subjects your system to infection through various discovered exploits that have been patched by SP2, but not having it makes users complicit in the spread of malware to others on the internet, especially to those in your address book.
The problem you are experiencing now may well be from a malware infestation not recognized by Norton which is an anti-virus ap and doesn't address other types of malware.
By the way, a router is not a substitute for a software firewall. You need both. Do you even have mac addresses locked down in your router, which is not nor was it ever intended to be a substitute for even a hardware firewall?
