I've always been somewhat confused by this. I've noticed a bunch of my DVDs (both anamorphic), I get 2 viewing angels. One, like starkiller and others have said do leave little bars on the TV. They're very miniminal, compared to letterbox (which leave huge black bars on the TV). I always thought this was letterbox enhanced for widescreen TVs. On other DVDs (especially recent TV shows, b/c of HD widescreen), they fill the entire screen, no black bars at all. What's the difference between the 2 anamorphic viewing angels? Is it a setting on my DVD player/TV?
