Whatever. Doesn't that mean nonwidescreen? Cuz unless you have a huge widescreen TV, those bars are an unforgivable pain. Croping a little off the sides is less evil than the excessive space those bars take up.
NTSC is/was the Broadcast standard for US, Canada, and Japan (among a few others) for SDTV that was in use from 1946 till the digital change over. The HDTV broadcast standard is called ATSC. by Default NTSC is a 4:3 broadcast but it can be 16:9 SD. If you take a 2.35 (very wide) picture and Pan and Scan it for a 4:3 screen you can lose as much as 1/3rd of the picture so its not just a little of the picture your losing but a lot.
