Additional information about Linux can be found here:
Can I use the WinTV-HVR-1850 with Media Center?
The WinTV-HVR-1800/1850 will work with Windows 7 or Windows Vista Media Center. Just use the driver provided on the Hauppauge WinTV-HVR Installation CD. Since the WinTV-HVR-1800 is dual tuner, you will be able to watch and record analog cable TV channels and ATSC digital TV channels at the same time. Vista Media Center does not currently support clear QAM digital cable TV.
The WinTV-HVR-1800 can be made to work within the Windows XP Media Center application provided you have the latest updates (roll-up 2) for MCE installed. This update provides support for digital (ATSC) tuning and will allow MCE to recognize the WinTV-HVR-1800 as a tuner in its configuration. Without the latest updates MCE will give the error message “No tuner hardware found”.
Under Vista, there would not be any additional updates required for the WinTV-HVR-1800 to operate in Media Center.
What type of channels will I receive with the WinTV-HVR-1850?
NTSC Analog CableTV or over-the-air analog TV: You can use your cable TV from the wall to connect to the WinTV-HVR-1800 and receive all of your basic Cable TV channels. You can also use a roof top antenna to receive "over-the-air" TV.
Note: After June 2009, most areas in the United States no longer broadcast over-the-air analog signals.
ATSC over-the-air digital TV: Supports all ATSC formats, up to the high definition 1080i format!
Note: For ATSC digital TV, a rooftop/out door antenna is recommended for optimal results/signal strength.
ClearQAM cable TV Channels: Clear QAM digital cable TV channels are unencrypted digital cable TV channels. Clear QAM allows users to watch unencrypted digital TV channels from their cable TV provider without a set-top box.
Note: WinTV v7, WinTV v6, Microsoft Windows 7 or Windows TV Pack 2008 for Vista are required for clear QAM reception
Note: Check your local cable TV provider for clear QAM reception over your cable TV network.
Can I receive high definition digital TV with the WinTV-HVR-1800 through Cable or Satellite Box?
Can I listen to FM radio with WinTV-HVR-1850?
What type of recordings can I make with the WinTV-HVR-1800?
Using the WinTV 7 application the WinTV-HVR-1800, will record in a transport stream (TS)
For ATSC and Clear QAM digital TV recordings, the recording format and bit rate is exactly the same as the broadcast format (i.e. ATSC 1080i is recorded at 1080i).
For NTSC analog cable TV recordings, our HardPVR is used to create Transport Stream files (TS)
Note: TS files can be converted to MPEG files using options in the WinTV 7 configuration menu.
Note: The WinTV 6 application recording are in MPEG format for both digital and analog.
Note: Not all recordings made with ATSC/QAM signals are DVD compliant
Can I record one show while watching another with the WinTV-HVR-1800?
Black video window or choppy video when watching a digital TV channel
If you are watching a digital TV channel and you see choppy video, no audio or a black screen, then it is possible your PC is not fast enough to decode and play the digital TV channel you are watching. Please verify that your system meets the minimum requirements for using the HVR-1950
Digital TV, especially ATSC high definition digital TV, is very CPU intensive. Many graphics cards have special built-in hardware to speed up decoding of high definition TV channels.
On graphics cards without special video decoding features, you can often improve the playback performance by using the Video Renderer settings located in the settings menu of WinTV 7. To open the setting menu click on the “gear” button located in the lower left of the WinTV 7 screen.
The default mode is EVR. The other modes are VMR9, VMR7 and Overlay. Each mode uses a different process to render video. Try each mode and use the one which gives you the best results. To use hardware acceleration put a check in the box “use hardware acceleration when possible. This will allow your graphics system to use hardware acceleration for video decode. Note: graphics hardware acceleration does not work on all systems. After making a change in video rendering settings Wintv must be restarted to take effect.
If you are using WinTV 6 then the render options are part of a separate program called Primary. Changes in the Primary applet must be made with the WinTV application closed. Open the Primary program by going to Start – All Programs – Hauppauge WinTV – Primary. After making changes close the Primary applet and open the WinTV application.
WinTV crashes on a Dell Vostro desktop

I receive a "Low bit rate" error message when using Windows Media Center in Windows 7.
Click to view the information from Microsoft.
What file size will the recorded videos be?
Digital Broadcasts (ATSC or QAM)
The file size of a digital signal capture depends on the bitrate of the digital signal. The bitrate is set by the broadcaster and cannot be user configured. Bitrates for digital signals can range anywhere from about 1.2 Mbits/sec up to 19.3 Mbits/sec. Most of the time these bitrates are variable and not constant. Capture sizes for ATSC & QAM recordings are approximately 1.7 Gigabytes per hour up to 8.3 Gigabytes per hour.
The WinTV application has to convert analog signals to digital in order to record. There are four recording profiles. The following list shows recording file sizes for burning to 4.3Gb DVD:
Best - Approx 1 Hour+
Better - Approx 1 1/2 Hours
Good - Approx 2 Hours
Fair - Approx 3 Hours
WinTV v7 does not open or opens and then disappears?
This can be caused by a corrupt Channel database so you will need to uninstall and reinstall. First you need to go to start, all programs, Hauppauge Wintv and in that folder run
“uninstall Wintv7” (or remove Wintv7 using control panel "add/remove programs) then you need to remove the backup channel database.
Windows Vista, 7 and 8 go to C:\program data ( this folder is a hidden folder so if you do not see it you need to “show hidden folders “ in your search
Options) once you can get to this folder you will see a folder label “Hauppauge” delete this folder.
Windows XP go to C:\documents and settings\all users\shared documents\application data ( this folder is a hidden folder so if you do not see it you need to “show hidden folders “ in your search Options) once you can get to this folder you will see a folder label “Hauppauge” delete this folder.
Then download the latest version of Wintv7 located in the support section of the website and reinstall (note: you must have your original CD to validate the download.)
WinTV v7 error messages and what they mean
First time installation of WinTV v7 or during a reinstallation: “WinTV board not found” or “No TV tuner available”
Step 1: Check the status of your Hauppauge TV tuner drivers in Windows Device Manager
- Click Windows Start, click on Control Panel and click on Device Manager
- In Device Manager, click on Sound, video game Controllers
- You should see your Hauppauge product
Step 2: If the Hauppauge device has a yellow exclamation mark
Click on the Hauppauge device to open it. If you see the following:
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
This appears to be a bug in Windows 64 bit OS since the Hauppauge Windows drivers are signed.
The following is the easiest fix to Error Code 52 on Windows 7 or Windows 8 64bit.
- In Device Manager, right click the Hauppauge product under Sound Video and Game Controllers with the exclamation mark and select Uninstall. If you have a USB product you might see multiple listings, please right click the first one on the list. (For this example we will use the WinTV-HVR-950Q. )
- On the Confirm window please check the box for “Delete the driver software for this device” and click OK
- Repeat the uninstall for the other two WinTV-HVR-950Q entries (Note: you won’t be asked to ‘confirm device uninstall’ again)
- Once the drivers are removed, right click on Sound, Video, Game controllers and click Scan for Hardware Changes
- Windows should now look online automatically for the 950Q drivers
- Take a look after a few minutes if the drivers are installed automatically properly under Sound Video and Game Controllers.
- If they still come back as “unsigned” try the procedure again
Errors when running WinTV 7: “TVserver cannot Start” or “.NET framework" errors

Then you need to remove the backup Channel database:
- Windows Vista, 7 and 8: Go to C:\program data ( this folder is a hidden folder so if you do not see it you need to “show hidden folders “ in your search Options) once you can get to this folder you will see a folder label “Hauppauge”. Delete this folder.
- Windows XP: Go to C:\documents and settings\all users\shared documents\application data ( this folder is a hidden folder so if you do not see it you need to “show hidden folders “ in your search Options) once you can get to this folder you will see a folder label “Hauppauge” delete this folder. Then download the latest version of Wintv7 located in the support section of the website and reinstall (note: you must have your original CD to validate the download.)
Settings.xml file is corrupt or missing
Solution: Uninstall WinTV v7 and then reinstall WinTV 7
- Click Windows Start -> Control Panel and then click Programs and Features

Making connections to your WinTV
Here is a chart which shows some of the things you need to know about each type of connection
Connecting to an over-the-air antenna
Cable or satellite TV set top box
Cable or satellite TV set top box
Connecting to a cable TV wire from the wall (Digital QAM)
|Which type of TV can this connection be used with?||Over-the-air digital TV||Cable or satellite TV
set top box
|Cable or satellite TV
set top box
|Cable TV direct connection|
|What types of video do I select when scanning for channels in the WinTV application (Device Setup Wizard)?||Digital ATSC||Analog TV (cable/antenna)||External inputs
(S-Video or Composite video)
|Digital QAM or
Analog TV (if available in your WinTV tuner)
|What remote control do I use to change channels?||WinTV remote control||Remote control from your set top box||Remote control from your
set top box
|WinTV remote control|
|Notes||You can use a roof top antenna for best reception.||
Most set top boxes allow you to switch to Channel 3 or 4. When you scan with WinTV, it will pick up the TV signal on the correct channel.
Some satellite receivers use channels 60, 70 or 73. But when you scan for Analog TV channels, WinTV will pick up whatever channel is being used by your set top box.
Most set top boxes have A/V connections on the back, which can go into the WinTV's A/V input.
Some cable TV networks transmit analog TV channels, so we recommend scanning for both Clear QAM and analog TV.
Not all cable TV networks transmit clear QAM. Check with your local cable TV operator for the availability of clear QAM in your area.
