Default Sync to VBlank killing performance for 60fps video

I'm seeing this message a a lot from mplayer on my nvidia based HTPC but not on my slower laptop with an onboard Intel gpu.

2.66Ghz C2D (nForce mobo)
Nvidia 210
1920x1080 display @ 50Hz

2.00Ghz C2D
Intel onboard
1200x800 display @ 60Hz

Example video (h.264 640x480 60fps)

mplayer -fs -vo vdpau -vc ffmpeg12vdpau,ffh264vdpau,ffvc1vdpau,ffwmv3vdpau, -ao pulse

System too slow message, audio out of sync yet cpu is < 10%

Switching to 1080p60 seems to help a little.
Dropping to 720p60, video plays fine
Switching to -vo xv, video stutters every few seconds
Switching to unscaled -vo x11, plays back fine
Switching -ao alsa/null, no difference

Any ideas? It was the same situation previously using the onboard nForce gpu before I upgraded to a 210.
