If you are in the TWC SW Ohio system (Dayton/Cincy region) please post here telling whether (or not) you get 8-blinks (and have to call TWC) at least once every month (if you use a Tuning Adapter). One of the TWC National Cable Card Support desk people told me that TA's are programmed to require re-authorization every 30 days and he suspects our system isn't doing this. If this is correct everyone with a TA should be getting 8-blinks once a month. If this really is what's happening it's probably worth trying to make a stink about it with higher ups at TWC. It's conceivable that rebooting a TA might force a refresh of it's authorization, so if you DON'T get 8-blinks every month but you DO reboot your TA more often than that, please include that info in your post.
