${${${(M)${(f)"$(mplayer -vo help)"}:#	*}/	/}/	/:}

Assuming they don't change the output format, this will find all
relevant lines by virtue of the beginning TAB, discard them, then replace
the second tabs with colons in case you want to use those descriptions
(and why waste free descriptions?).

All blocks of whitespace in that line should be literal TABs, by the
way.

I've had a glance and it looks good.

To just suppress the first line, it would be something like
  ${${(f)"$(mplayer -vo help)"}[2,-1]}
but I don't know what the output looks like so I expect Clint's
answer will be more useful.

You'll need to declare expl local in these functions too.

What is the more command in the pipeline for?

You can probably replace the pipeline with some sort of zsh
substitution which would be more efficient but less readable. In this
case, it'll be something like:
   list=( ${${(f)"$(mplayer -ac help)"}[8,-1]%% *} )

You can also make it more efficient by using `compadd -a list'

typo - should be alphamap

You might want to look at the _path_files -W option here to complete
from within ~/.mplayer/Skin and /usr/local/share/mplayer/Skin.

wrong language for the word card.

You can call _x_display to complete display names. Or use _x_arguments instead
of _arguments to get a number of common X arguments automatically.

-fb should take a parameter I think for the device.
