Yes, the WinTV-HVR-1950 can be used in Windows 7, Windows XP or Vista Media Center.
Please note: you will only be able to configure WinTV-HVR-1950 as either a Digital tuner or an Analog tuner. You will not be able to switch between Digital and Analog channels.

What type of channels will I receive with the WinTV-HVR-1950?

NTSC Analog CableTV or over-the-air analog TV: You can use your cable TV from the wall to connect to the WinTV-HVR-1950 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 get HD with the WinTV-HVR-1950 through my Cable or Satellite box?

No. The WinTV-HVR-1950 has an ATSC over-the-air digital TV receiver built-in and supports all ATSC formats, up to the high definition 1080i format . The WinTV-HVR-1950 will support ATSC broadcasts that are currently being transmitted over-the-air. It will not be able to decode HD broadcasts that come through your cable or satellite box. The WinTV-HVR-1950 also will support clear QAM cable TV channels through your direct cable TV line if available from your cable TV provider.

What type of recordings can I make with the WinTV-HVR-1950?

Using the WinTV 7 application the WinTV-HVR-1950 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 Channel while watching another with the WinTV-HVR-1950?

No, the HVR-1950 is a single combo-tuner, so it will only record and allow you to view one channel at a time.

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.

I receive a "Low bit rate" error message when using Windows Media Center in Windows 7.

Microsoft has released Windows Media Center patches for the "Low bit rate" error message.
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.

Analog Broadcast.

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.)

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.
