4:3 films on Blu Ray shown on a 4:3 display produce a 1:1 compressed 'postage stamp' sized image with black bars on all sides on a 4:3 display.
This is a BIG miss because it means Blu Ray is not both forward and backward compatible for all types of displays.
Not sure how big this miss is. I doubt seriously that many people who have legacy 4:3 interlaced displays are going to invest in Blu-Ray. There are still some 4:3 HDTVs out there, but one would logically set the BluRay player to widescreen for these displays. 



How expensive would it have been to include the means to expand the 4:3
film image to fill a 4:3 display?
Sounds like just another whoops from an industry that has often struggled to understand Digital TV and digital standards. 



Is this just some additional code in the disk or in the player?
Why did the Blu Ray authors choose to ignore the case of 4:3 film shown on 4:3 displays? If it's just some code, it can't be too much of a financial impact on the manufacturers. 

Sounds like they are techno-snobs to me.


Keep in mind that BluRay is being marketed as an HDTV accessory.
