I have one hopper and two joeys, and a sling adapter. Mostly works fine (except not with Firefox) but...I have noticed on a few occasions when failing to get the sling adapter working with my laptop, that my hopper is using two tuners. Each tuner is on a different channel. When I check this by watching the TV on the hopper, I can switch back and forth between the two channels, but both tuners stay occupied. If one of my joeys is also using a tuner, then of course the sling adapter cannot watch TV as there are no free tuners. I cannot figure out (1) how the hopper can occupy two tuners (2) how does this happen and (3) how can I release a tuner. So far, resetting the hopper is the only way I am able to do free up tuners, which is a pita, especially if I am traveling. Does anyone have answers to these questions? I have called tech support and not been able to get them to understand the problem, let alone come up with a solution.
