Without the -vsync I'm getting an annoying twitch or jerk in the movement 
of the picture every now and then. The amount seems to depend on how much 
there's movement in the video. E.g. watching hockey is a nightmare because 
there's 2-5 jerks / s.

On the other hand, with -vsync the picture is like a postcard. There's no 
flicker, twitching etc and the quality is better than from dvd or dvb-stb. 
Hopefully someone can point out a fault in my configuration.

I tried all the available audio outputs: oss, sdl, alsa but no effect. I 
used the -framedrop just to illustrate that with -vsync mplayer can keep 
up the sync by dropping frames.

Unfortunately this doesn't seems to help. =(
