Blu-ray in Windows XP…
Installing a Blu-ray CD drive in your XP machine is not enough to be able to read the contents of Blu-ray CDs. You’ll also need to download and run a special UDF Reader from here…

…when you extract the files R-Click on thdudf.inf and choose “install”, and finally restart your system.
You should now be able to view the contents of Blueray CDs in XP.
