Article ID: 810243 - View products that this article applies to.
Microsoft has released a supplement to update the Stream Buffer Engine (SBE) and Encryptor/Decryptor (EncDec) components that are included with Windows XP Service Pack 1 (SP1). If you want to play files that were recorded in Windows XP Media Center Edition (.dvr-ms files) on a computer that is running Windows XP SP1, download the "Update for Windows XP Service Pack 1 (KB810243)" update from the Microsoft Windows Update Web site. To download this update, visit the Microsoft Windows Update Web site:
The SBE was first included with Windows XP SP1. Programs can use the SBE to seek, pause, and record a live video stream without interrupting the stream. Transitions between live and recorded content are seamless. Currently, the SBE supports MPEG-2 video and digital video (DV) sources at capture rates up to 20 megabits per second (Mbps). Shows that are recorded in Windows XP Media Center Edition are stored with a .dvr-ms file name extension. Whether you can access .dvr-ms files by using DirectShow depends on the copy protection policy that is set by the content owner, the broadcaster, or both. If the broadcaster designates a program as being copy protected, you can use full personal video recorder (PVR) functionality by using a Windows XP Media Center Edition-based PC (including recording the program for later viewing), but you cannot play those files on other PCs or devices. You can play back any unprotected TV content that was recorded with Windows XP Media Center Edition on the following devices:
