Sorry PhilC - not sure what you mean. In Poser 5 if you were in the graph editor you could grab the green play head bar (cursor would change to an arrow pointing right & left). You could then move (scrub) the green bar to the right or left and as long as your AVI was compressed you could watch the AVI movie play. So you could scrub back and forward to get a sense of timing. Poser 6 only updates the AVI movie when you stop at a frame and release the left mouse button - this is completely useless.
