Simply put, the wider the film format a given movie was shot in, the wider the black bars above and below the active video area are going to appear...period. It was true with 4:3 TV sets, and still holds true with 16x9 displays.
Personally, I absolutely abhor TV channels that crop native aspect ratios to "fit the screen," even HD channels; it destroys the original intent of the movie directors' careful framing of their films, the ONLY exception being movies that were shot in Super35 (full aperture framing); these can be modified practically at will under the supervision of Directors for video mastering and subsequent transfers purposes.
Movies like T-2 and other Cameron's movies were shot in Super35 which for theatrical presentation were formatted in a bastard (as I call it being that is not true anamorphic lensing) "scope" format; these can be altered for video transfering without messing up the original framing intent.
True Lies is a good example of this; HBO had a new HD transfer of this movie done for them, which was aired in the 16x9 AR video format some time back--it looks absolutely gorgeous, and its framing suffers very little in the translation when compared to the "scope" version.
Oh, yes...as with SD widescreen transferred movies, the addition of 33% of more vertical lines of resolution also aids 16x9 transfers for after all black bars are ACTIVE video too!

Man, I wish HD was anamorphically "enhanced"!
Anyway, the most extreme widescreen movies to be encountered are those that were filmed in Ultra-Panavision; 1959's Ben-Hur, The Greatest Story Ever Told, The Allelujah Trail, The Fall of the Roman Empire, and Mutiny on the Bounty are examples of this (a fairly recent transmission of Ben-Hur by Cinemax finally gave this glorious widescreen Epic its overdue HD treatment, something that can be sampled to a lesser extent in the magnificent DVD box set that Warners put out not long ago. Can't hardly wait Ben-Hur is given the Blu Ray treatment too! Oh, well...HD video tapes of that transmission and 35mm IB Technicolor road show plus S-8mm prints of this movie will keep me at bay until that happens.

But now looks like am going to need a KURO to view it with!
