Video capture cards are used to get the picture from the cable, aerial, or satellite television source into the PC.
They decode and capture the video signal from the channel you want to view or record. Most cards include a tuner to capture an specific TV signal (called 'tuner cards'). Video capture cards without tuners do exist, but these are not commonly used with MythTV. Sometimes people mistake video capture cards with video display cards which provide the output to the (tv)screen.
If you visited this page to pick a tuner card, then jump to the section Cards tested with MythTV.

Types of cards
Analog framebuffer cards
These cards (also called frame grabbers and software encoders) are usually based on a chipset like the Bt848/878 or Conexant cx2388x, and decode broadcast NTSC, PAL, or Secam television. These cards deliver an unencrypted data stream to MythTV, which then encodes to MPEG-4 or RTjpeg using software encoders. Advantages of this type of card are:
- Low cost
- High flexibility -- you can choose your encoding method and employ filters prior to encoding
- If you have the CPU power, MPEG-4 produces better quality with smaller file sizes than the MPEG-2 used with most hardware encoding cards
The main disadvantage of this type of card is the high CPU requirements. Depending on your encoding settings, you may need close to 1GHz of CPU speed to handle a single encoding stream, and more if you have multiple cards or want to play back while recording. MPEG-4 is particularly demanding; for systems with weaker CPUs, RTjpeg consumes less CPU time at the cost of larger file sizes and more digital video artifacts.
Analog Hardware-Encoding Cards
These cards, currently the Hauppauge PVR cards, the AVerMedia M179 and any other card which supports the V4L2 MPEG Encoder API, have a video processor onboard which compresses the tuned video signal into an RTjpeg, MPEG-2, or MPEG-4 program stream before sending it into the computer. The advantages of these cards are:
- Greatly reduced load on the entire machine (with certain technical caveats). This is particularly important for machines with weak CPUs or when using multiple tuners in one system.
- The reduced load means that your video stream is less likely to suffer from encoding "hiccups" if a process causes the system to become momentarily too busy to process the video.
- Most hardware-encoding cards output an MPEG-2 stream, which can simplify backing up to DVD.
The main drawback of this type of card is that you're limited to the video format and encoding options supported by the manufacturer (usually MPEG-2). You can transcode to MPEG-4 after recording to save space, if desired, but this requires post-record processing and will degrade quality slightly.
Digital Hardware-MPEG cards
Digital broadcasting (for DVB and ATSC at least) is in the form of an MPEG-2 transport stream, so unlike analog capture cards, there is no need for any kind of onboard encoding engine, the required program stream is extracted and handed directly to the computer for viewing or saving. Some cards have a hardware Program ID filter (hardware pid) which means the card can extract the required program stream from the transport stream itself.
In either case, the computer power required to save a MPEG-2 transport stream (but not view it) is very small, being only what is required to shift data from the PCI/USB bus and save it to disk.
Confusingly, many useful tools for working with MPEG-2 transport streams have "dvb" in their names, even though they work just as well with MPEG-2 transport streams derived from "ATSC" broadcasts.
Some digital capture cards also support analog (NTSC or PAL) transmissions, usually via a frame grabber. If your digital capture card lacks such hardware and you want to record both digital and analog transmissions, you'll need to buy a separate analog capture card - either a frame grabber or a hardware-encoding card.
With the world moving towards digital broadcast standards, this type of card is likely to become dominant in the next few years.
Cards tested with MythTV
MythTV basicly supports all cards that are supported by the LinuxTV module. So you can choose any card thats registered as supported on the | LinuxTV site.
Because its practically impossible for us to test all these cards, we have added the cards that we have tested on MythTV below. Of course all the other "LinuxTV supported cards" should work as well.
If your card is not in this list and works with MythTV then we would appreciate it if you add it here so others can benefit from your experience. For specifications about a card you can go to | LinuxTV site or the site of the manufacturer.
If you make an entry here, it is very useful to show the numerical PCI ID or USB ID of the card. This will allow people reading your information to be positive it applies to their card. Examples in this wiki are Compro_VideoMate_TV_Gold_Plus (PCI) and DViCO_FusionHDTV_DVB-T_Dual_Digital_4 (USB). On Linux you can get this information with

Analogue cards (Hardware Encoder)
When watching analogue television a hardware encoder makes it easiers for you computer to process the tv signal to a digital signal.
Note: Hauppauge is no longer shipping any analog only (PVR) cards due to pressure from FCC.
- iTVC15 family of MPEG encoders supported by the IVTV drivers
- V4L2 MPEG encoder API card (Kernel 2.6.18 and later)
- Hauppauge WinTV-PVR-USB2 (MPEG2 encoder box with USB2.0)
- Cards based on the Conexant cx23416 MPEG with cx88 pci brigde (Conexant blackbird reference design)
- Hauppauge WinTV-PVR-Roslyn (P/N: 28552 on the TV Tuner).
- ADS Tech Instant TV_Deluxe - PTV305 (Kernel 2.6.20rc2 and later)
- Must use use proper encode firmware, cx88_blackbird module, and use V4L2-ctl with myth
- Matrox Marvel G200/G400 MJPEG encoders
Analogue cards (Software Encoder versions)
Because these cards don't have a encoder your computer needs to work harder to convert the analogue signal to a digital signal.
Note: Hauppauge is no longer shipping any analog only (PVR) cards due to pressure from FCC.
- BrookTree (bttv) based cards. NOTE: The bttv page includes kernel parameters and links to vendor specs.

Please add your information to the heading "Cards tested with MythTV". This section is outdated and will also be moved there.
Because all the specifications in this matrix are also available and more up-to-date at | LinuxTV wiki (the module we use for MythTV), its unnecessary to update this matrix.

Cards that don't work
Here you find an overview of the cards not working with MythTV. In general the cards listed here as "not working" are the cards not supported by the LinuxTV module. So the fact that these doesn't work isn't a MythTV issue.
- ATI All-in-Wonder cards
The ATI drivers provide a kernel module for basic V4L support which allows for capturing video from the device as it is playing. They do not, however, provide the tuner functions necessary for MythTV to select channels. Instead, they implement their channel tuning using the Xv extensions of X-Windows. A solution might be to patch the MythTV source code to recognize the ATI hardware and use Xv frequency changing to change the channel rather than solely relying on the V4L tuning functions. Then it would depend on whether the V4L support for capture is adequate enough in the ATI drivers for MythTV to work. It also might be possible to use an externally called Xv channel changing utility to change the channels.
The ATI All-in-Wonder card cannot (it is said elsewhere on the internet) send video across the PCI bus. It can only show video on the VGA output on the card. It is on this basis that neither the card nor drivers are appropriate for use with mythtv.
- PVR-350 all functions work, but TV-Out isn't well suited for Myth, since it isn't accelerated and the MPEG decoder isn't well supported any longer.
- Hauppauge WinTV-HVR 1600. Includes both an ATSC high-def tuner and an analog cable TV tuner, but is apparently not yet supported by the IVTV drivers. There is a beta driver in development. http://linuxtv.org/hg/~hverkuil/cx18/. Analog NTSC has partial support.
MPEG Tuner Card caveats are mostly that since these cards tend to be PCI busmasters, you may have to be careful how you put them in your machine (ie: which slots), where your VGA card is, and possibly what kind of motherboard you select, if you're planning on doing something silly like building a 10-tuner machine with 5 Hauppauge PVR-500's.
