Well, sadly, multithreading doesn't allow mplayer to do filtering in
multiple threads still; after last upgrade I could play any stream on
single core (well haven't tried higher than 1080p / 30fps), but
performing nearly any kind of filtering on 1080p is still impossible
(and even heavy filtering on 720p).
What saves is that most HD streams don't need any filtering, but slight
sharping can help some of these; so far, unsharp filter + most of 1080p
content is no go, as mplayer can't utilize more than one core for that.

But for weaker systems, multithreaded decoding is really wonderful.
