Viewer For Raw .Video Files From Speco DVR

Does anyone know of a viewer for files pulled directly from the hard drive of a Speco DVR? They have a .video file extension and I haven't been able to open them with anything.

Can you put (a small) one on Dropbox or other file sharing, (if its not sensitive of course)?

Sometimes its just a container in a container, sometimes you can just change extension to make it work. Dahua DAV files for instance can be renamed .mp4...

Here's a sample file. The mp4 trick does not work for sure. Thanks for your response!
