Yeah, for some reason it lies. I wasn't able to get anything to play the .mov files that the app generates. You have to convert them first. You could probably even convert it from .mov to .mov and it would work.
Also, partyflavor, great vid, got a little dizzy in the parking garage.

Definitely post a vid when you get a chance to try the slow motion setup. I doubt we can expect quality high-speed footage... Just imagine the possibilities of a cell phone that could record at 120 fps. Probably not on the top of the to-do list...
