hey.. give this a try..
Edit->Keys->Delete option box..
in there set everything to all.. (all objects, all keys), that should get rid of all of your animation in the scene..
Now, I have a question.. my playback speed is set to 30fps (1.25x) and when I playblast my sound lines up with the animation, however when I render it doesn't.. any ideas?
Good luck
