Consider the following scenario.

• You use a Windows Vista-based computer.
• You use a widescreen monitor that is attached to a video card.
• The video card uses a Uniform Memory Access (UMA)-based video card driver.

Note UMA-based video card drivers are associated with integrated video chipsets. There is no indicator in the operating system that informs you whether a driver or a chipset uses UMA architecture.
In this scenario, if the Windows Experience Index (WEI) score is greater than or equal to 3.0 in Windows Vista, slide show pictures are not displayed in the center of the screen. Instead, the slide show pictures are displayed on the left side or the right side of the screen.

Consider the following scenario:

• You use several pictures to create a Windows DVD Maker slide show in Windows Vista.
• You use the Change slide show length to match music length option together with several song files.
• One or more of the song files are MP3 files that are encoded with a variable bit rate (VBR).

In this scenario, you find that the slide show length does not match the song length. Therefore, there are sections of silence between the songs.

When you try to play Windows SlideShow in Windows Vista, you may experience either of the following problems:

• You see a black screen when you use a full-screen theme.
• You see a black placeholder where a video is supposed to play.

In Windows Vista, you experience poor performance when you view images by using the Slide Show feature in Windows Photo Gallery. For example, transitions between the images may be choppy.

When you view a slide show in Windows Photo Gallery by using the Pan and Zoom theme, you may experience poor playback quality. Some of the symptoms may include playback that is irregular or that contains glitches.

Note: This problem only occurs for high-end video cards.
