A problem in the Service Pack 2 update for Windows XP may keep owners of
AMD-based computers from using the long-awaited security package, according
to Microsoft.

However, an AMD representatives said the chipmaker believes the problem has
only occurred, so far, with one application, Sigma Designs' Realmagic
Hollywood Plus DVD Decoder. Microsoft also identifies the application as
being able to cause the problem.

Microsoft said in its advisory that PCs with 64-bit AMD processors may
restart repeatedly after installing Service Pack 2, if those machines are
also configured to enforce so-called data execution prevention (DEP) and
contain hardware that requires a driver software known as Mpegport.sys.
Sigma Designs' Realmagic Hollywood Plus DVD decoder application is one such
application that uses the driver, the software maker said.

Microsoft says users may be able to resolve the problem by configuring a
so-called DEP exception. AMD also recommends that people affected by the
problem do so. Otherwise, Microsoft advises AMD users to remove SP2
altogether.

The AMD problem is the latest in a slew of issues that have dogged SP2 since
it was first released to PC manufacturers at the beginning of August. By
mid-month, Microsoft had detailed some 50 different software applications
and games that may encounter problems with the update.
