Is anybody else having issues with the 10 second skip back function on their Hopper 3? Mine seems not to work on the first press. The picture will freeze momentarily but then continue from the current location. A second press of the button will get it to do the skip back but even then it isn't always a full 10 second skip. More like 5 seconds sometimes. Two rapid presses seems to get it to do the full 20 second skip back like it should. I've tried restarting the unit but that doesn't make any difference.
