Just my  2 cents on this. Using the sun audio output  has in many
times resulted in a performance improvement for me. The default OSS
audio output has to be emulated by the native API, which may result in
some performance tradeoff.  So , try -ao sun . Apart from this the
mplayer docs come with various tricks you can use to optimize the
output, one  good one is to use a cheaper and poorer software scaler 
( -sws 4 ) .
I'd suggest try  a combination of -vo xv -ao sun , as your preferred
video / audio outputs. and see if it helps. -vo sdl -ao sdl have
better results sometimes. Do play with their combination.
