Use the file command or tcprobe to indicate what kind of movie it is. It may be an .avi file using a DivX codec.
Here is a link to the "divx4linux" home page:
Also, check if you have a win32codec package that you can install. If not, google for the terms "divx daily build"
The infomation I found on the web indicates that the camera produces either AVI or WAVE movies. I'm not familiar what kind of video a WAVE file is.
