No, I am not confused.  Component can do 1080i, yes.  But up until
recently it was only normally used with CRT TVs, at 720x576, typically
from DVD players.  That is the way most people have seen component
video.  And in quality it is very similar to S-Video.  I can not say
that I have ever tried S-Video at 1080i, but it is likely possible as
typically S-Video and component outputs are created by the same
hardware in a chip, with just an extra stage at the end to create the
two S-Video colour signals from the three original colour signal.
