Consider the following scenario:
Weak TV Signal
The TV tuner is unable to receive the signal for the channel you have selected. Adjustment to the signal may be necessary to receive this channel reliably. Please try to select this channel again. If the problem persists, contact your TV service provider.
This message is displayed even though the signal is not weak and there does not appear to be any noticeable dropped frames or loss in video quality.
This message can be erroneously displayed by Media Center under certain circumstances.
To resolve this issue, use one of the following methods to modify the registry.

Did this fix the problem?
The registry value WeakSignalDroppedThreshold specifies the maximum percentage of dropped packets before Media Center displays the Weak TV Signal message. If the registry value is not set, the default value is 10%. The steps in the Resolution section specify to set it to 50% (32 hexadecimal). The side effect of setting this to a higher value is that it may in some cases prevent a valid Weak TV Signal message from appearing while watching Live TV in Media Center. However, in the case of a valid weak signal it may be obvious to the user, due to dropped frames or other video artifacts, that there is a signal strength problem for that particular channel.
