Don't know the answer, but in my two LG TVs, one maybe 4 years old and the 
other 3 years old, it works great. Although it took forever for any OTA 
broadcasters to start using it. There's only the NBC O&O and the Fox O&O who 
are using it now in the DC market, on their SD subchannel, as far as I can 
tell. In both cases, I was happily surprised to finally see widescreen SD 
programs that didn't require me to change modes manually.

One of my favorites, for real-time viewing. Always something interesting to 
watch. I have no idea whether it's expensive to transmit AFD. I can only guess 
that the excuse for using postage stamp 16:9 is that if one assumes that many 
out there don't have AFD, then even the most inept users can see an undistorted 
(if small) 16:9 image that way?

One interesting note is that international TV networks seem to be migrating to 
all-16:9 quickly now. Of the programs MHz Networks transmits, the first to 
switch was France 24, years ago now. Then came Aljazeera and Russia Today 
(postage stamped both) fairly recently. The Korean Arirang has some 4:3 and 
some 16:9 (anamorphic squeeze). Just seems like it's time to stop transmitting 
postage stamped 16:9.

Zooming in on postage stamp images is not really satisfying. Poor image 
quality. SFD in my experience always stretches anamorphic squeeze. Much nicer.
