Yes, the WinTV-HVR-1975 can be used in Windows 7, Windows XP, Vista or Windows 8 Media Center.
Please note: you will only be able to configure WinTV-HVR-1975 as either a Digital tuner or an Analog tuner. You will not be able to switch between Digital and Analog channels.

PAL/NTSC Analog CableTV or over-the-air analog TV: You can use your cable TV from the wall to connect to the WinTV-HVR-1975 and receive all of your basic Cable TV channels. You can also use a roof top antenna to receive "over-the-air" TV.

DVB-T2 over-the-air digital TV: Supports all DVB-T2 formats, up to the high definition 1080p format!
Note: For DVB-T2 or DVB-T digital TV, a rooftop/out door antenna is recommended for optimal results/signal strength.

DVB-C cable TV Channels: DVB-C freeview digital cable TV channels are unencrypted digital cable TV channels. DVB-C allows users to watch unencrypted digital TV channels from their cable TV provider without a set-top box.
Note: WinTV v7 or higher versions, Microsoft Windows 7 or Windows TV Pack 2008 for Vista are required for DVB-C reception
Note: Check your local cable TV provider for DVB-C reception over your cable TV network

No. The WinTV-HVR-1975 has an DVB-T/T2 over-the-air digital TV receiver built-in and supports all DVB-T/T2 formats, up to the high definition 1080i/p format. The WinTV-HVR-1975 will support DVB-T/T2 broadcasts that are currently being transmitted over-the-air. It will not be able to decode HD broadcasts that come through your satellite set-top box. The WinTV-HVR-1975 also will support DVB-C free-to-view cable TV channels through your direct cable TV line if available from your cable TV provider.

Using the WinTV application the WinTV-HVR-1975 will record in a transport stream (TS)
For DVB-T/T2 and DVB-C digital TV recordings, the recording format and bit rate is exactly the same as the broadcast format (i.e. DVB-T 1080i is recorded at 1080i).
For PAL/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 App's configuration menu.

Note: Not all recordings made with DVB-T/T2/C signals are DVD compliant.

No, the HVR-1975 is a single combo-tuner, so it will only record and allow you to view one channel at a time.

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-1975

Digital TV, especially DVB-T2 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 App. To open the setting menu click on the “gear” button located in the lower left of the WinTV App 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.

Digital Broadcasts (DVB-T/T2 or DVB-C)

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 DVB-T/T2 & DVB-C 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
