Support: How to rescan for TV channels

How to re-scan for channels in the WinTV v8.5 (or WinTV v8) application

Here is a video tutorial on re-scanning for channels

Step 1: Delete the channel database

We recommend that you delete the WinTV channel database before you re-scan for channels, especially if you think that your channel line up has changed. To do this, close the WinTV v8/v8.5 application and then run this program:

c:\Program Files (x86)\WinTV\WinTV8\WinTV8.exe -emptydb

Step 2: Re-scan for channels

  • If you open the WinTV application, in the lower left there is an icon which looks like a 'gear'. Click that icon.
  • Go to Devices tab
  • Find your Hauppauge tuner under the Device list. Select it.
  • Then click Tuner Setup
  • Select your TV format: digital or analog.
    This is a screen shot from the WinTV-dualHD, so if you have a different Hauppauge tuner, you might see different video formats listed.
  • Then click Next
  • And click Next again and the WinTV application will start scanning for channels. When done, you will see a list of all channels which were found.

This example is from the WinTV-HVR-955Q. If you are connecting to a cable TV box with coax, choose 'Analog TV (Cable/Antenna)' and you will find either channel 3 or 4.

Notes:

- If you are connected to a cable TV or satellite box through a coax cable, and you scan for Analog channels, you should find the signal on channel 3 or 4.

- The WinTV-dualHD and the WinTV-quadHD are digital only. So you cannot connect these devices to a cable TV or satellite box (which send their signal on channel 3 or 4, which are analog). Instead, you should use a Hauppauge WinTV-HVR (the HVR stands for hybrid: analog and digital) such as the WinTV-HVR-955Q.

- If you do not see all of your channels, check the cable connection to your set top box or re-position your TV antenna, and then go back to Step 1 and scan for channels again.
