Microsoft has released an update for the Windows Media Center TV Pack for Windows Vista. This update is intended for computers that are running the Media Center TV Pack in Windows Vista Home Premium or Windows Vista Ultimate.

The update for Media Center TV Pack for Windows Vista resolves the following issues:

• When the .wtv files are synched by using the standard Windows Media Player process for third-party formats, the .wtv files are put under the Video library instead of under the Recorded TV library.
• Windows Media Player does not display the progress bar during media playback.

Consider the following scenario: In Windows Vista Media Center, you set up a manual TV recording to occur near or right after daylight saving time ends. After the recording has finished, when you go to view the recording, you find that Media Center did not record the correct television program as expected. Instead, it appears that Media Center recorded a television program that was one hour later than expected.

Note: For most of the United States, daylight saving time (DST) starts at 2:00 A.M on the second Sunday of March. Daylight saving time reverts to standard time (ST) at 2:00 A.M on the first Sunday of November.

You install the October 2008 Cumulative Update for Windows Media Center for Windows Vista (955519) on a Media Center system that has digital cable card tuners installed. When you perform back-to-back recordings, the first recorded TV show plays back correctly. However, the second recorded TV show plays back only audio.

In Windows Media Center in Windows Vista, you manually start a recording. When you look under Recorded TV for the recording that you started, Media Center does not indicate that the recording is in progress.

Even though Recorded TV does not indicate that the recording is in progress, the manual recording is successful.

Consider the following scenario:

• You have a Windows Vista-based computer that has Windows Media Center TV Pack installed.
• The computer has multiple graphics adapters and has multiple monitors connected.
• You play a DVD or a TV program in Windows Media Center.
• You start Windows Media Center in a secondary monitor, or you move it to a secondary monitor while the video is playing.

In this scenario, the video that is displayed on the second monitor may appear garbled. This problem occurs only on computers that have certain graphics hardware installed.

Assume that you are running Windows Media Center TV Pack on a Windows Vista-based computer. When you try to search for television content by using an element such as the title, a keyword, an actor, or a director, you may not receive any results. If you run the search immediately after you finish the “Set up TV” process, this is the expected behavior because the indexing process takes some time. However, even about four hours after the “Set up TV” process is complete, you may still be unable to search for television content.

If you have Vista Premium or Ultimate, this may be available to you soon. Keep reading →

When you open the Microsoft Windows Media Center TV Pack and tune to a channel that is listed in the Electronic Program Guide (EPG), you may receive one of the following error messages:

Error Message 1

No TV Signal

Error Message 2

There is currently no TV signal detected for this channel. The channel may be temporarily off-the-air, or you may need to adjust or reconnect your TV antenna.

When you open Windows Media Center TV Pack for the first time on a computer that has a Quadrature Amplitude Modulation (QAM) tuner installed, and you choose to set up your TV signal, one of the optional configuration steps will prompt you to scan for channels. When the channel scan completes, you may find a smaller than expected number of QAM channels listed in the Electronic Programming Guide (EPG).

For more information about how to remove a channel from the EPG if you receive a “No TV signal” error message when you tune to the channel, click the following article number to view the article in the Microsoft Knowledge Base:

When you watch video or Live TV on a Windows Vista-based computer, you experience the following issues.

Issue 1

While you are watching Live TV in Windows Media Center, you put the computer into standby. Then, you resume the computer from standby, and you continue to watch Live TV. Although video playback starts successfully after you resume the computer from standby, the video playback application stops responding (hangs) after about two seconds.

Issue 2

You play video content that contains multiple video resolution formats. For example, the content contains formats of both 1440 × 1080 pixels and 1920 × 1080 pixels. In this situation, the video playback application stops rendering after the content changes from one format to another.

For example, assume that you play the video content, you click Pause in the video playback application, and then you try to drag the slider to the right side of the seek bar. In this situation, you cannot drag the slider, and the application stops responding.
