I have been experiencing a problem locking OTA signals since 265. The problem seems to be getting worse. My 811 is only used to watch CSI and Judging Amy in HD. Or to watch SD when the 510 is recording something I want to watch later. After 265 I immediatly started having the 49% problem, which I never had before. The 2 digital stations I get, CBS and FOX, both show signal strength of over 75% WHEN they will lock. Now, for the last 2 weeks I cannot get the CBS to lock at all. This happens no matter the weather conditions. It also seems that I have to reboot the 811 for various reasons, green dotted lines, no sound on OTA, scrambled guide, much more than I had to before. I have checked antenna alignment and it has not moved. Nothing has changed EXCEPT 811 software and the problems are getting worse. I have had great patience with the 811 but it is wearing out
