This doesn't match what I see with vo_vdpau (using driver version
180.22). Playing with "-vo vdpau -benchmark -nosound" I get higher
framerates than monitor refresh rate (with both hardware and software
decoding). This is unlike for example -vo gl which IS limited to monitor
refresh rate at default settings. An older version of VDPAU may have
differed in that regard, I don't remember for sure. Are you sure the
behavior differs on your machine? If so, what driver version do you use?
Do you have composite enabled? Any other settings which could possibly
affect it?
