Because out of hundreds of region-1 DVDs, I've found only 2 that don't 
use soft telecine, at least for the main feature. If ffmpeg didn't 
support soft-telecined VOBs as input, then it could not be used to 
decode so-called "NTSC" DVDs, HandBrake wouldn't work, MPV wouldn't 
work, and LVC wouldn't work.
