I think unless you purchase DashCam viewer you really cannot do much other than view the video files. Also I think DashCam view is the only one that will let you see the GPS data, speed and route info. That data is imbedded into the video file. Although with the free version I think you can export the GPS data to a GPX file, but it seems to me I had to do a modification to the file so I could read it.
I purchased it and it's registered as the full version. Even the developer hasn't been able to come up with a good reason it's not working. He is very responsive though, so I'm not going to say bad things about it or him.
