Its a 25 meg file, I honestly had the same problem 2 years ago and found a download to play it, but I worked for a different company and no longer have the file. I think it was an Argus player (maybe) but everything I see now only connects to the IP of a camera. I am going to have to swing by and get more info on the DVR I guess.
it's the third one listed here:
