Microsot published a cumulative update for Windows Media Center — KB 981078 fixes following issues:
- If there’s a revoked version of PlayReady PC Runtime installed when you use WMC to play protected content, a “Copy Prohibited” overlay message or a black screen is displayed. After you apply this update, overlay message will direct you to appropriate PlayReady PC Runtime update on Microsoft Update website.
- You reference a backup database when guide database in WMC is corrupted. If you set a manual recording on a channel that’s not listed in backup database, Mcupdate.exe process crashes.
- Schedule data may disappear in regions that use in-band guide data. For e.g., schedule data disappear in Digital Video Broadcasting (DVB) regions.
- WMC crashes when you use an invalid path for a recorded TV location.
