Fixes for the Windows Media center Low Bit Rate overlay messages(KB981130):
Windows Media Center monitors the incoming bit rate of live TV. Without this monitoring, the bit rate drops very low when the analog TV input is weak or does not have a signal. This causes a black screen or a static screen to be displayed.
However, the method that is used to monitor the incoming bit rate on analog signals is too sensitive. This may cause a false detection of a low bit rate.Install this update if you see low bit rate message on Windows 7 Media Center when watching live TV.
