Where's My CDs?!

XPSP3 stable version is out. Decided to download and install it. Then I though, why not integrating the SP3 with my XP CD with no SP.

...copied XP CD to HDD. Fine.
...extracted the files from the SP3 .exe file. Fine.
...extracted the boot image from the CD. Fine.
...slipstreamed the SP3 to the XP files. Fine.
...created an ISO file of the package. Fine.
...opened CD burning software and chose to burn the image. GODDAMN! ¤*&#§¤%€#! I'm outta CDs!

I'm even out of DVDs. Haven't burned a CD in couple of years. I guess it's time to go to a CD-r shop.
