I developed an AIR app to export SWF to PNG sequences: 
http://swfrenderer.kurst.co.uk

We developed it because flash was skipping frames and animation was not overly 
smooth on CPU intensive movies (be it code or timeline). We also had a few 
issues with the CS5 PNG/Movie exporter. It works with timeline animation and 
dynamic / coded animations (AS2/3) -  and works well as long as tweens use 
frames  instead of timecode.  (for tweenmax, it's the useFrame property for 
tweens).

Hope it helps someone...
