When you open the Microsoft Windows Media Center TV Pack and tune to a channel that is listed in the Electronic Program Guide (EPG), you may receive one of the following error messages:
Error Message 1
No TV Signal
Error Message 2
There is currently no TV signal detected for this channel. The channel may be temporarily off-the-air, or you may need to adjust or reconnect your TV antenna.
The Windows Media Center TV Pack has an "Auto Select" option which removes channels that have a weak signal from the EPG. To run the "Auto Select" option to check the list of available channels and to evaluate the signal strength for each channel, follow these steps:
Start Windows Media Center.
In the Start window, scroll to Tasks, click Settings, and then click TV.
Click Edit Channels.
Click Auto Select.
The "Auto Select" option tests each channel. Based on whether a strong or a weak signal is found, the "Auto Select" option puts a check mark in the box next to the channel. As soon as the detection process is complete, you have to click the "Save" option to save the newly selected channels to the EPG.
Note Depending on the total number of channels to scan, the "Auto Select" option could take more than an hour to finish the detection process.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

Start Windows Media Center.
In the Start window, scroll to Tasks, click Settings, and then click General.
