What kind(s) of TV signal do you receive? You can select more than one.
If you are planning on recording or viewing High Definition (HD) programming with MythTV, check this box.
This works fine for OTA (over-the-air/antenna) feeds, and can work even if you have cable, too. If you have only cable, the situation can be a bit more complicated; see "Digital cable" below.
If you have digital cable (High Def or otherwise), and you want to use it with MythTV, check this box.
Note that the media cartels don't like you being able to record digital and/or High Def programs, so the cable providers make this situation tricky. See the GNHLUG MythTV page for more on this.
A capture device is the piece of hardware which sucks a TV signal into a computer. These will generally include a "tuner" (used to pick out one station from many), and maybe also an "encoder" (which converts the signal to a more suitable form). There are quite a few products on the market, but not all of them work with MythTV. We are trying to limit the event to the hardware we know works well.
The video card (AKA display adapter) is responsible for generating a picture for you to view. Again, we need to know what to expect, and we are also trying to limit the event to hardware we know works well.
On a normal PC, this will be attached to a "monitor". You can do the same with your MythTV box. If you have a TV with VGA or DVI inputs, you can also attach your MythTV box to that. Getting any kind of TV-out working (composite, RF, S-VHS/S-video, component, etc.) is beyond the scope of this effort.
