We've noticed lately that if we scroll through our recordings list, we can only get so far before the screen goes black then dumps us back out to live TV. This happens on the Hopper (no sling). On the Joeys, we can continue to scroll, but when we get to the point the Hopper would have stopped, tiles will be missing or we'll see duplicate tiles. If we switch the order of the list from DVR Date to A-Z, then we're able to scroll through everything without issues. Is this a known problem? It seems like software to me since we can work around it just by changing the sort order.
