I've still got "too SLOW" both for 'mplayer -zoom -xy 0.7 -lavdopts skiploopfilter=nonref'
as well as for 'mplayer -vf scale=1280:760  -lavdopts skiploopfilter=nonref'.

Note 'mplayer -zoom -xy 0.7 -lavdopts skiploopfilter=all' works fine, but
'mplayer -vf scale=1280:760  -lavdopts skiploopfilter=all' gives "too SLOW" again.

Since I don't need resolution more than 1280x760, I'm thinking about encoding this
to x264 and relax about these issues completely :-).
