This has bugged me for quite some time. I've not tried Menu/Guide but have tried bringing up the guide directly to no avail. Once in a while the guide will appear at which time I can chose the OTA channel and continue. Part of the 722 code must be old school in that if the satellite signal is lost, it's not really interested in letting you do anything like view the guide or change channels. It apparently assumes all is lost and you should just wait. So, when storms are coming, I'll tune to an OTA ahead of time and leave it there. That never fails. I can see in the PIP window that the satellite is out. As long as I don't switch to that view, I'm OK.
