I had Hoppers and changed to Hoppers with Sling. Before the switch I transferred many recordings to my EHD. After the switch I can't move any of them back to the Hopper. They all get transfer error 855, "An error occurred while transferring events to your "Hopper Set Top Box". I have 2 Hoppers with Sling and both do that, so it's not an EHD issue. The recordings can be viewed fine from the EHD but just won't transfer. It's not a big deal but I often want to view a recording from one room in another room, and you can't view another Hopper's EHD from another location. Is this a known problem? Have others run into this?
