I am not seeing less but removing the letterbox on the SD stream. The
original 16:9 program is thus filling the entire 16:9 screen.
On the HD stream the original 16:9 program is both letter boxed and
pilloried, it is locked and cannot be cropped except with VideoReDo ($$).
The original HD program (16:9) is NOT transmitted on the HD stream as HD,
the quality has already been reduced by adding the letterbox and pillars.
KQED has reduced this practice and does not happen as often now.
But, KQEH on (54.1, 9.2) and many other KQED Inc. streams present 16:9
reruns letter boxed in SD. (9.1 is the only HD stream out of eight streams I
can receive from the two transmitters)
The practice of adding the letterbox and pillars is not limited to KQED but
KCSM (Now in process of being sold as it was costing the college too much
money and the Internet is now more useful for delivering college programs)
also does it, much more often to save money.
I see a lot of commercials on the major networks that are letter boxed and
pilloried, they will go away someday, who cares.
Note: The San Francisco Bay area had all the analog stations duplicated on
DTV transmitters very early and our news went to HD very quickly. One did it
and the rest had to follow very quickly. The conversion to HD from SD is
almost complete here.

Thus I watch a lot of 16:9 programs using VLC media player to crop and fill
my 16:9 screen.
When KCSM adds the letterbox and pillars and transmits the result in HD, I
just suffer through it as VideoReDo ($$) takes too much time and it reduces
the quality more as it is getting ready to burn a DVD anyway.

It depends, part of the painting might be all that I want on the wall.
I would like all the programs that were produced in 16:9 to be viewed in HD,
but the bandwidth is not there to do it. KQED tried during it's testing
phase to stuff way too much into one transmitter (Actually both perhaps, the
cut off of analog is now a distant memory) and the results were dismal.
Really horrible. They are sending all that they wish with HD programs sent
once or twice and then repeats letter boxed and pilloried over and over.
