Character animations not in sync when recording movie from sequencer

Hi

I have sequence in sequencer that I’d like to record (save to avi), but when I do that the characters keep playing their animations at the same speed, even though each frame of the sequence takes much longer than normal to actually render and record.

So for each frame of the movie, the character animation has advanced 4 maybe 5 frames.

The result is in the recorded avi, my character animations are playing way too fast.

Is there away I can stop this ?
