ATI vient de publier sur son site un communiqué de presse de Microsoft reconnaissant le problème décrit depuis quelques jours par de très nombreux utilisateurs de cartes ATI All-in-Wonder. La fonction Tuner TV ne marche plus (en version PAL uniquement) si DirectX 9.0b a été installé (par exemple à partir de Windows Update). Par rapport à la version 9.0a, DirectX 9.0b intègre un patch de sécurité critique. Microsoft recommande donc aux possesseurs de cartes All-in-Wonder qui n'ont pas encore installé DirectX 9.0b d'attendre la résolution du problème et d'installer à part le patch de sécurité. Ceux qui l'ont déjà installé et souffrent du problème peuvent tenter de revenir à une sauvegarde système précédente à l'aide de la fonction System Restore (sur Windows XP uniquement).
"Microsoft has investigated reports that the DirectX 9.0b release adversely affects a subset of ATI products with PAL TV Tuners. We acknowledge that a change to DirectShow TV Tuner support in this 7/25/03 release has impacted PAL TV capture. We are developing a patch with high priority to correct this issue. Please note that this change is not related to the security fix identified in bulletin MS03-030, although both fixes are in the DirectX 9.0b release.
This problem is known to affect only PAL devices on Windows 2000, Windows XP Home and Professional, and Windows Server 2003. The problem is isolated to the DirectX 9.0b End-User Runtime (dxwebsetup.exe) and DirectX 9.0b Redistributable Runtime for Software Developers (dx90b_redist.exe). Customers installing only the DirectShow Security Fix for DirectX 9.0 and 9.0a (KB819696), a ~900KB update which is different than dxwebsetup.exe, by Windows Update Critical Updates or Automatic Updates will not be affected.
If DirectX 9.0b has not been installed and the customer has a PAL product, we recommend installation/verification of DirectX 9.0a at this time. To address the MS03-030 security issue, please perform one of the two possible methods of installing the security patch:
* Install the patch manually from http://www.microsoft.com/downloads/details.aspx?FamilyID=22f990cb-e9f9-4670-8b4f-ac4f6f66c3a2&DisplayLang=en, selecting the appropriate language.
* Install the same patch, titled Security Update for Microsoft Windows (819696), from Windows Update Critical Updates, or verify that this patch has been installed in the Windows Update Installation History if automatic updates are turned on.
For customers with DirectX 9.0b already installed, we are making every effort to provide a patch at the earliest possible date. On Windows XP, the customer should consider using a restore point to revert the system to a pre-DirectX 9.0b state (http://support.microsoft.com/default.aspx?scid=kb;EN-US;306084), and then follow the steps above for applying the security patch. We will provide an update to ATI on a target date as soon as we have distribution commitments.
If a customer has performed a DirectX upgrade or patch without using the DirectX 9.0b runtime and is experiencing a problem, please contact directx@microsoft.com with details."
