INTRODUCTION

Consider the following scenario:

  • You have a Windows 7 computer configured with a digital TV tuner.
  • Windows Media Center is configured to use the digital TV tuner.
  • You launch Media Center and then choose Live TV to watch TV.
  • You change the channel.

In this scenario, soon after changing to a certain channel you may consistently see a message that resembles the following:

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.

  • Some improvement, but not enough - a film on Film4 recorded ok from 1pm to 3pm, then another started at 5pm ok but failed after 30 minutes.

  • I tried setting the WeakSignalDroppedThreshold up to 99, and the quality threshold down to 1; still no joy: it recorded only the first 20 minutes of BBC1's match of the day on Sunday morning. I'm about to give up on WMC for digital TV recording.

  • The Weak TV Signal message has spoit recordings several times, most recently last Saturday night and again tonight (another Saturday night). I will try the FixIT and hope that works. If it does not I will have to seek an alternative to Windows Media Center.
