Newbie Question: Does anyone know if you can access the video on an external hard drive.? I am getting an Hr-24. From my research on the internet, the video files are encoded in a stream.str file on the hard drive. I want to be able to back up the external hard drive to another external hard drive in the event the main external hard drive with all my shows crashed. Can you back-up the contents from one drive to another? Can i then play the archived videos on the external drive on a pc?
