I purchased a new Openbox X3 HD Satellite Receiver in June and as far as moving my Dish and scanning in about 10 Satellites it has worked well. My question is the X3's instruction Manual isn't much help re how to play Video files from a 2 TB Seagate External Hard Drive I got with some Movie Files for Xmas. I don't want to destroy my upgraded files which were done from a flash drive plugged into the USB Port on the front of the X3. Does anyone know if I can just plug in my Seagate External Hard Drive into the X3's USB Port then select Video Files to Play on the X3 without causing a problem with my software Upgraded Files? Is there a special set of steps I need to go thru? Any replies would be very much appreciated.
