SYMPTOMS
When you start a slide show in Windows Photo Gallery in Windows Vista, the slide show stops, and you receive the following message:

Loading…

When this issue occurs, you do not see the slide show pictures. You may hear audio for the slide show if the slide show includes audio. This issue occurs even though the Windows Experience Index rates the computer's Graphics and Gaming graphics with scores of 3.0 or more.



CAUSE
This issue may occur if the following conditions are true:
 * Your display does not support the progressive scan mode or the non-interlaced scan mode in the current resolution. For example, the screen may only support the interlaced scan mode in the current resolution.

Note Some displays only support the interlaced mode in specific resolutions. For example, many plasma and LCD televisions use the 480i or the 1080i modes. In these examples, the letter &quot;i&quot; signifies &quot;interlaced.&quot;
 * Windows Vista tries to use the DirectX Exclusive mode to draw the images. When the DirectX Exclusive mode is used, the progressive scan mode is always used.

When you play a slide show, Windows Vista uses the Windows Experience Index ratings for graphics to determine whether to use the DirectX Exclusive mode or the GDI+ mode to draw the images. If the system is using a more powerful graphics device, Windows Vista uses the DirectX Exclusive mode. Otherwise, Windows Vista uses the GDI+ mode. When Windows Vista uses the DirectX Exclusive mode, the progressive mode is always used. However, if the display does not support progressive mode in the current resolution, you may experience the issue that is described in the &quot;Symptoms&quot; section.



WORKAROUND
To work around this issue, use either of the following methods, as appropriate for your situation.

Method 1
Use a display that does support progressive mode in the selected resolution.

Method 2
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

Note We do not recommend that you use Method 2.

Edit the registry to force Windows Vista to use the GDI+ mode. To do this, add a DWORD value that is named WinSATSCore and that has a value of &quot;0&quot; to the following registry subkey:

To do this, follow these steps:  Click Start, type regedit in the Start Search box, and then click regedit.exe in the Programs list.

If you are prompted for an administrator password or for a confirmation, type your password, or click Continue. Locate and then click the following registry subkey:

HKEY_CURRENT_USER\Software\Microsoft\Windows Photo Gallery\Slideshow

 On the Edit menu, point to New, and then click DWORD Value. Type WinSATSCore for the name of the DWORD, and then press ENTER. Right-click WinSATSCore, and then click Modify. In the Value data box, type 0, and then click OK. Exit Registry Editor, and then restart the computer.</li></ol>

To restore the default settings and to enable Windows Vista to use progressive mode, delete the WinSATSCore DWORD value.
