I had this connected when I first got it and it worked great except for the pixelating...sound worked great then too. I disconnected it and decided to wait until the switchover is made hoping it would behave better. Well the channels I was able to get before seems on update are not receiving now...also the sound is not working., not even static.....yet the sound does work on my analog tv... had sound before on the tuner but not now....any ideas?? Thanks!
