Assume that you have a document that contains custom properties. In Windows XP or in any pre-Windows XP operating system, the Content Indexer service can index these custom properties. However, in Windows Vista and in Windows Server 2008, the Content Indexer service cannot index these custom properties as expected.

Consider the following scenario: You are using an OpenCable Unidirectional Receiver (OCUR) device that is connected to a Windows Vista-based computer. You put the computer in standby or hibernate, and then you resume the computer. In this scenario, when you try to watch live TV in Windows Media Center, you receive the following error message:

Restricted Content – Display Driver

If you wait for 30 seconds after you resume the computer from standby or hibernation, and then try to watch live TV, the problem may not occur. In other cases, you may have to restart the computer to resume live TV playback.

Because of this problem, scheduled recordings may not be recorded.
