FIX: Some protected TV content may not play after you change the system time on a computer that is running Windows XP Media Center Edition 2005 with Update Rollup 2 (912453)


The information in this article applies to:

  • Microsoft Windows XP Media Center Edition 2005 Update Rollup 2

SYMPTOMS

After you change the system time on a computer that is running Microsoft Windows XP Media Center Edition 2005 with Update Rollup 2 (MCE), some protected TV content may not play. If you have rolled back the system clock, you may receive the following error message when you try to play some protected TV content:
Restricted Content: Restrictions set by the broadcaster and/or originator of the content prohibit playback of the program on this computer

CAUSE

The Microsoft Windows Media Digital Rights Management (WMDRM) system uses various checks to make sure that a user has not tampered with the WMDRM system. When you roll back the system clock, the WMDRM system detects that the system time has changed. Therefore, the WMDRM system may disable playback of content that requires a time-based license.
