jerky playback can be caused by buggy sound drivers...

ok here's a patch for linux/timer-lx.c
under cygwin it now uses high precision timers.
you need to define HAVE_NANOSLEEP in config.h, since its default disabled

However using these new timers doesn't result in any smoother playback the
frames rendered too late/ too fast still increase quite rapidly for example
i got a small divx5 avi file (total duration = 9 secs) with audio 48KHz,
16bit,2 ch, 192kbit and video 25 fps 640x256 this file got 52 frames
rendered too late and 58 frames rendered too early, (no frame drops) its
just an example, all files show this behaviour. Again Windows media player
plays them ok

also I tried -vo null, but it makes no difference.
Then I tried using the -nosound option  and .... then it plays very smoothly

any idea where to look next?
