You have to perform a custom installation to upgrade XP pro to home prem.
XP pro can be upgraded to home prem if you do a custom installation:
http://support.microsoft.com/kb/932616 Boot off the DVD.
Select home premium *without entering a product key* first install:

just like it shows you to do in the dailytech article I linked to.
Then, when installation is complete, run the install program again, but
this time not booting from the DVD, but from within Vista, and this
time enter the product key which is good for home premium. Also,
do not select Upgrade - select Custom (advanced). Yes, it is a
clean install - you'll have to back up your stuff then reinstall it.
Custom is the way they let you go from XP pro to home prem.
XP pro will upgrade non-custom to business or ultimate only.
