Multiple unknown channels are visible in the Program Guide after you run AutoScan in Windows XP Media Center Edition 2005 (897087)

SYMPTOMS

After you run AutoScan to scan TV channels on a Microsoft Windows XP Media Center Edition 2005-based computer, many unknown channels are shown in the Program Guide. Some of these channels display snow or static images. However, Teletext information may appear correctly.

CAUSE

This issue occurs because when Windows XP Media Center Edition 2005 scans for TV channels, Windows XP Media Center Edition 2005 verifies a table of expected frequencies in the region. Sometimes, Windows XP Media Center Edition 2005 may detect the bleeding of the signal into the neighboring frequencies. If the bleeding to surrounding frequencies is strong enough, the Program Guide may show this kind of bleeding as unknown channels.

RESOLUTION

You can resolve this issue by editing the channel line-up to remove the unknown channels from the guide. To edit the channel line-up to remove the unknown channels from the guide, follow these steps:

Press the green Start button on the remote to open the Windows XP Media Center Start page.
Highlight and press the OK button on the remote for the following items:
1. Select Settings, and then select TV
2. Select Guide, and then select Edit Channels
Remove the checkmarks from the unknown channels.
