I have searched the threads for keyword B-Band and do not see a thread on this. If there is one that I did not find, if you would be so kind to point me to it, it would be appreciated. Over the last few days when the HR20 reboots, it takes first to a screen saying the B Band Filters are not installed and they need to be. This is something new (at least for me). The stranger part of this is that my B Band Filters ARE installed. Anyone know what this is all about?
