Microsoft has released another rollup update for Media Center 2005 machines running Update Rollup 2. Specifically this update corrects the following issues as well as those contained in all Rollup Updates since Rollup 2. 

Video may stutter after you resume the Windows XP Media Center Edition 2005-based computer from standby (S3) or from hibernation (S4).

The Windows XP Media Center Edition 2005-based computer may take five minutes to resume from hibernation. The computer may appear to stop responding and display a black screen during this time.

Media Center may stop responding when you press ALT+TAB.

Video may stop responding in Media Center if the computer is using certain models of dual tuners. This problem occurs when both tuners are being used or when you are using a Media Center Extender for Windows XP Media Center Edition.

You do not receive a signal when you use digital TV in the Taiwan region. With this update, Media Center now supports tuners that produce both analog and digital signals for use in Taiwan. The update does not affect digital and analog tuners in other regions.
