ArcGIS 10 documentation says that an animation can be exported to either .avi or .mov (quicktime). I only see the .avi option in my drop-down list? What am I missing.
EDIT: Quicktime is installed on my computer
You'll need the Quicktime codecs.
You can either download and install quicktime from Apple.
Or if you don't want all the junk that Apple bundle together, there's the QuickTime Alternative - though there's no guaranteeing that ArcGIS will pick that up.

Alternatively: Known bug
See: http://support.esri.com/en/bugs/nimbus/TklNMDYzMTYz - its been reported as a bug in ArcGIS 10. Apparently one that's been open for a long time.
i wonder that do you have quicktime installed on your machine? maybe ArcScene cant communicate without quicktime..
i guess that i have encountered such a problem in the adobe after effects too. you can try to use QuickTime Alternative 3.2.2 here.
i hope it helps you...
