With heavy storms training across the area all night I wasn't surprised to find my Dish 622 with a partial signal loss early this morning. It doesn't take much to knock out 129 here. Recalling something I read the other day, I opened the guide and selected another channel, At first it showed signal loss but within seconds a transparent banner displayed saying the HD channel was unavailable and the receiver was switching to the SD channel. I was able to watch the SD version of several channels until the storms finally passed. As soon as I tuned to a channel it automatically switched to the SD channel. Wonder if this is a new feature in the latest software or just something I never knew about. It's great and will mean far fewer rain fade complete losses of service.
