povray*.png -> povray-anim.mpeg?

I've been trying to find a way to turn the output of my povray animation run into an mpeg. When I use imagemagick with the mpeg2encode I get numerous vbv_delay overflow and vbv_delay underflow messages. The quality of the animation when viewed in kmplayer is also not very good. Is there a better way to go about this? Thanks, STH
