Video capture cards are used to get the picture from the cable, aerial, or satellite television source into the PC (compared to video display cards which provide output). It decodes and captures the video signal from the channel you want to record.

Types of cards
Analog framebuffer cards
Analog Hardware-MPEG cards
These cards, currently the Hauppauge PVR-250 and Hauppauge PVR-350 and the AVerMedia M179, have a video processor onboard which compresses the tuned video signal into an MPEG-2 program stream before sending it into the computer. The tends to greatly reduce the load on the entire machine (with certain technical caveats), and these cards are recommended for.. well for all systems, really, but specifically, for systems with more than one, and especially more than 2 tuner cards.
Digital Hardware-MPEG cards
Digital broadcasting (for DVB 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 DVB program (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.

Cards that don't work
- 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.
- Hauppauge WinTV-PVR-Roslyn (P/N: 28552 on the TV Tuner).
- Hauppauge WinTV-PVR-USB2 (MPEG2 encoder box with USB2.0)
- http://pvrusb2.dax.nu/ a bare but apparently functioning userspace driver, no V4L so no MythTV for now.
- http://justiceforall.free.fr/pvrusb2.html A V4L driver for this card, but I'm not sure if it'll work with mythtv ;).
- http://www.isely.net/pvrusb2.html a driver by Mike Isely, actively maintained unlike the others. Is reported to work with MythTV.
- Cards based on the Conexant cx23416 MPEG encoder chip not already supported under ivtv (e.g. PVR2000).. development work has been done but cannot be considered a good solution for mythtv (yet).
- 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.
