My original Hopper is extremely slow since the firmware was upgraded. It literally takes 20-45 seconds to bring up the DVR and then varying amount of seconds (up to 15-20) once a selection is made. Now I want to move my DVR contents to an EHD. I do not want to buy the one offered by Dish. The USB powered units seem to work for some and not for others. Is there a current list of EHD that will work on my Hopper and allow me to transfer to my new H3? Thanks
