On a Windows Vista-based computer, you try to play a video file of a certain format by using Media Center Extender for Windows Media Center. However, the file does not play. Additionally, you receive the following error message in the thumbnail preview:
Cannot Play Video
Note You do not receive this error message in a standard error message dialog box.
This issue occurs if Media Center Extender does not support a particular video file format. Media Center Extender supports video file formats that are a subset of the video file formats that are supported by Windows Vista. Therefore, although certain video files may play correctly in Windows Media Center, these files may not play at all in Media Center Extender.
To work around this issue, use a video-editing program to convert the file into a format that is supported by Media Center Extender.
In Windows Vista, Media Center Extender for Windows Media Center supports the following video file formats:
Windows Media Video 9 main profile (.wmv)
WMA standard audio
Max resolution 720 by 480
Max bit-rate 4 Mbps
WMV content may be Windows Media DRM-protected
MPEG-1 and MPEG-2 standard definition (.mpg)
MPEG-1 layers I and II audio
Standard Definition DVR-MS (Recorded TV) at all quality settings (Fair through Best)
You can use Windows Media Encoder to re-encode affected videos into the Windows Media Video 9 format together with WMA 9 standard audio. This format will play correctly in Media Center Extender. To obtain Windows Media Encoder, visit the following Microsoft Web site:
