Since installing a large Vista update last week, I have been unable to get video attachments to play directly out of Windows Mail. I get the audio but no video. When I open Media Player, while the audio is running, I see the picture. This would be cumbersome but workable except that I can't close the video at this point without rebooting. It has been suggested to me that I should save the file and play it outside of Windows Mail. I tried this but the video still gets locked up and I have to reboot to turn it off. Should I reinstall Windows Mail or Media Player or both? Video files from web sources such as Youtube work fine.
