Can somebody with one of these scan Gal17 and tell me if it actually can scan both polarities? The last 2 nights I've tried , I have watched it scan thru the freq but it never switches to the V side. It always scans the H side first and if it hits an HD signal it evidently borks it so that it will never switch to the other polarity. Even going back to set the polarity manually to V, it finds zero. Mine has the latest AC-3-fix software in it. Thanks!
