I have a new 522, mostly pleasant experience. I've followed all the posts, etc. Waiting on the PIP upgrade for sure. My problem is that the unit seems to loose all signal lock overnight. When I turn it on in the AM I have to go through the entire setup routine, find the sats, go through 2 sets of resyns, etc. Then, and only then will the guide download and finally the reciever will come alive. Any suggestions on how to avoid this every day. Obviously I'm not unpluging the unit. I've tried turning it off with the remote, and with the front pannel switch. Neither one changes the process.
