I have a security camera system at work & i need to pull video from it and view it on my MBP. The file it gives me when I output from the machine is an .arv, (which I have never heard of) but I cannot seem to find software (preferably freeware?) to read it. The system gives me a viewer ("DVR Viewer"), but it is an .exe, so it won't run on my system. Thanks for the help!
