i instaled a video card with bnc outputs to plug my security cameras on the computer, however, the software that came with the card kinda sucks! when i go in playback with the device no problems, the problem is playing it somewere else as the file extention is .dvr and not .dvr-ms i'm looking for a converter that realy works or since i know squat about computers maybe someone can tell me how to change the file extention from .dvr to let's say .avi or .dvr-ms thanks p.s. be very specific as i've mentioned i know s%&t about computers!
