Cause mplayer isn't complaining about dropped frames the best explanation is that instead of a constant stream of frames:
---*---*---*---*---*---*---*---*---*--- ...
We get something like this:
---***---------****------------*---*--- ...
That is usually caused by to long pipelines, e.g. the 3D rendering causes to long stalls, witch lead to burst of frames with the playback...
I'm also guessing that you are using Xv + "classic" mplayer, could you try the VDPAU implementation with mplayer2 instead? The result won't be better, but you get at least a good error message of what is going wrong here.
May I guess something?
