Have you removed the hard drive from the recorder? If that is the case then you have a number of issues to contend with.
First of all you may be trying to read the drive on a Windows based computer and the OS used in the stand alone recorder is most likely NOT using Windows.
Second, these devices are are required to use some sort of DRM (digital rights management) which would probably not allow viewing even if you were using the correct tools.
In short, you probably can't do what you are trying to do. This is by design.
