If you are having problems with electronic devices, it doesn’t hurt to check how you are connecting them together. Recently, the video camera we use for church seemed to start playing up. When I was recording a talk for Easter, it froze up when I was in full flow and then I couldn’t get more than a minute out of it… until I ordered a shiny new USB cable and it has been fine since.
I think that is indicative that the old cable was at fault. All I need now is a better way to check out my other assorted USB cables that is better than ‘test by failure’.
