I bought the adapter months ago, when they first became available. It caused my Hopper 2 to crash and reboot constantly. So I unplugged it, hoping that the problem would be fixed when the new software came down to enable dual tuning capability. When that software finally was released, it did not fix the problem. I SHOULD have returned it and got my money back, but I didn't. So my question is: Is this merely a defective adapter or is it just that I'm plugging it into a Hopper 2 instead of a Hopper 3. If so, is it likely to work if I get a Hopper 3?
