The KWorld Global Terminator is a TV *capture* card, meaning you plug in an
antenna, cable TV cable, or the like to *record* TV using the card. AFAIK, it
lacks the ability to send output *to* a TV. To be sure we're talking about
the same thing, check these URLs:
The first is the MythTV wiki entry for the card; the second is one of several
eBay auctions for the card. The second URL includes a photo with marked input
and output connectors, which is why I selected it. Note that both the coaxial
(TV) and composite/S-video connectors are for inputs.
For TV output, you need one of several things:
1) A regular computer video card and a separate converter box that takes the
VGA output from the video card and converts it to a TV standard suitable
for your TV, such as composite, S-video, DVI, etc.
2) A computer video card that includes a TV output suitable for your TV, such
as composite, S-video, DVI, etc.
3) A Hauppauge PVR-350. This is a video capture card that includes TV
output functionality that's supported by MythTV; however, that support is
likely to vanish in the future, so this isn't really a good option except
for the short term.
In theory, a device that combines a regular video card and TV capture card
functions would do the trick, too; however, I don't know if such devices
exist, aside from the Hauppauge PVR-350, which I don't believe can really be
used as a regular video card, at least in Linux. I'm not an expert on the
PVR-350, though, so I could be wrong about this.
Most people go for option #2 because a video card with TV outputs isn't much
more expensive than a video card without TV outputs, whereas a converter box
(needed for #1) is moderately expensive. They can be had fairly cheaply on
eBay, though, so if you've got an otherwise suitable video card, #1 might be
a reasonable way to go.
