any madvr+nvidia+59hz profile users here?

I m a mpc-hc+madvr user. When I dont use svp and use the regular nvidia 23hz (23.976 actually) profile for blu-ray content I get no dropped frames and no presentation glitches reported by madvr. But when I enable svp (and use the 59hz nvidia profile) I get like 5-10 presentation glitches every 20 minutes or so (no dropped frames however). The problem is not cpu related because the presentation glitches are there with heavy or light svp setting. Any thoughts anyone?
