Changing channels I get random No TV Signal Detected

[DOS4EVER]

Every once in a while when I change channels I will get the No TV Signal Detected message and I will have to keep changing until the picture comes back. It appears to be random with no defined pattern. Has anyone else noticed this? Is it a problem with the HomeRun or a setting in WMC?

This would be as good a place as any to get started.

Is there a fix for Windows 8.1 like this?

I presume this would be the same:

To resolve this issue yourself, use the following steps to modify the registry.

Exit Windows Media Center.
Run Regedit
Locate and then select the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectShow\Debug
From the Registry Editor menu, click on Edit->New->Key. Change the name of the new key to BDA.
Click on the newly created BDA key. From the Registry Editor menu, click on Edit->New->Key. Change the name of the new key to MSNP.
Click on the newly created MSNP key. From the Registry Editor menu, click on Edit->New->DWORD (32-bit) Value. Change the name of the new value to WeakSignalDroppedThreshold.
Right-click on WeakSignalDroppedThreshold and then click Modify. In the Value data box, type 32 and click on OK. (Leave the "Base" setting at the default, Hexadecimal.)
On the Registry Editor menu, click on File and then Exit to exit Registry Editor.
Shut down Windows and restart your PC.

I made the change. Lets see if it happens again. New build finished today.
