Mac Pro stuttering with h.264 1080p playback

Hi all,

I have a new pimped out Mac Pro (3.2Ghz 8-core, 16GB ram, 4TB HD, GeForce 8800GT driving dual monitors, a 30" and a 21") and I can't seem to playback h.264 1080p movies from my Canon 5d2 without occasional stuttering. This caused me to say WTF? I thought this beast could take on anything, but here it is, stuttering away. It will drop from 30fps to 26, 25, 29 etc randomly.

Does anyone here have a 5d2 or some other 1080p source footage encoded in h.264 that plays back smooth? Or does nothing play these videos without choking?

I'm hoping it's a setting somewhere.. The "play h.264 silky smooth" option that I've missed.

Thanks
