Screen Size Issue, help

I am playing DD (on PS3) and my TV screen resolution is 16:9, but the image in the game isn't filling the entire screen.

On Dragon's Dogma my screen gets shrunk by two black bars, one at the bottom and one at the top of the screen.

This widescreen effect is dramatically reducing the displayed image and makes the image looks stretched and squeezed.

Is there any solution to this? is there a way to set the screen size to fix it?

Does anyone else gets this?

No it is ok, it's not really stretched. maybe a furture patch will fix this, allowing screen to fit fully.

This isn't a very smart move by capcom.. Anyway I still get some framedrop when at night and there are several light sources active including healing spells, lantern, and other spells - the game slows like in slow-motion... 

 Do you have this slow-mo issue too?

I have heard that if you change your PS display settings to produce only 720p res' then the game will fit fully. But that will be a pain to swap all the time..

I have also heard that some players don't have this issue at all, no borders, how come?

One of them uses the same screen size (inches) like me, but he doesn't have the black borders !??
