go to the metreon(spelled worng I think) in SF. 
the tech museum doesn't work for regular movies. unless you get there really early and get the top seats and towards the center. 
I worked there when it was 1st built. they even said it, the dome does not work well with moves that are not sized to fit it. its like sitting the front row of a regular theatre. They said it back then. when the thought of movies not filmed in imax was frowned on. 
atleast with the metreon its just a gigantic screen in a regular theatre style setup
