OK, I'm a newbie so I am DEFINITELY not the person to rely 100% on, but let me give it a shot based on my experiences and "Dumb Moments."
(1) Make sure your STB is outputting normally. I have a SA 4200 Explorer and the Automatic screen-fitting on my 9631 wasn't working (I saw bars) because (a) the STB was set to 4:3 TV (b) even when I called Cablevision they did the EASY format which was just one 480-signal and 1080i; I needed to do the ADVANCED formatting which input 2 or more 480 signals, 720p, 1080i, etc. I forget the exact number but it was 5 or 6 HDTV signals.
(2) Make sure STB picture output is set to NORMAL and not STRETCH or ZOOM.
I'm not an expert on STB's or HDTV's by any stretch but the idea is that you want the STB to know that it's 'talking' to a 16:9 TV first and foremost.
Next, you want it to send the signal the way the channel is being broadcast: HDTV 16:9 signal sent as is, SD channels in 4:3 sent as is.
Then, when the TV gets the signal, IT can make the adjustment -- not the STB -- to fill the screen.
There might be a few channels that it doesn't work perfectly on; on these, you can either manually adjust via your TV remote or maybe it's possible on the STB to change the Format Output for that channel ONLY (DO NOT CHANGE IT FOR ALL THE CHANNELS. IF SINGLE-CHANNEL DIFFERENCES ARE NOT ALLOWED, DEFAULT TO WHAT'S BEST FOR THE MAJORITY OF CHANNELS).
Hope that helps a bit. Sorry I can't give you an iron-clad solution. I'm sure someone who has your TV set or someone with more knowledge will come along later today to pipe in.
