Well, firstly you should remove vhq option - you are using newer "mbd=2"
instead. Second, using vb_strategy=0 and vme=4 is useless, this is
default. Also I'm not sure that you are improving quality by specifying
predia & dia options, you should check it.
After those changes (also without them) the above string works for me,
but I'm using mplayer 1.0pre4 & cvs libavcodec. Are you sure you are
actually encoding video, you need to use "-ovc lavc" instead of "-ovc
copy"? Btw, in future always report complete command line.
