After going through the various animation tutorials in the Maya Help, I was introduced to the Playblast option. Unfortunately it doesn't seem to be working correctly, whenever I choose the option it only blasts(?) about 20% of the animation and the rest of the movie created is just a still.

I have a feeling that my processor may not be up to scratch (1.25 GHz), but does anyone have any ideas why Playblast isn't working properly for me?
