Component video is "color difference", S video is very similar to
component, as there is a Y(luminance) but there are 2 color signals
instead of one (R and B), the "difference" between R and B, makes G.
RGB contains much more video bandwidth then component video. Svideo
cannot handle HDTV, Component and RGB can.

Usually you need the filters and the termination resistors, and
depending on where you live, RGB devices may or may not be common.

I have 3 DVB-s cards in one machine, 1 is a FF, the other 2 are budget.
I run in softmode using softdevice 100% of the time. Even though I
don't receive and HDTV at all, using the output of a VGA card into a LCD
projector produces a much better picture.
The advantage to the FF card, is that it will work in a slow computer as
the card does all the
Displaying HDTV will need a powerful computer.
