Both of my cablecards started working on all channels after Charter did a cable card firmware update on the evening of May 29 (Riverside, CA). Turned on the set and there was a message on the screen about a cable card firmware update in progress. -- This may take 40 minutes. Do not turn off your equipment -- or something to that effect. Well, after two or three hours, the message was still on the TV, so I went to bed. Low and behold, the next day ALL channels came in fine on both cable cards for the first time since February install.
