Just 40 miles to my east, New Vision CBS affiliate WKBN-DT Youngstown OH 
is still running (at last check) two HD streams at 720p:  The CBS HD of 
WKBN, and the Fox HD feed of sister "WYFX".

WYFX ("Fox Youngstown") started out housed on two analog LPTVers, and 
then landed as an SD subchannel.  They've been putting it up in HD for 
about a month or two, downconverting WKBN's CBS HD feed to 720p from 1080i.

I didn't see it on a big screen, so I can't attest to the quality... but 
I did notice some encoder hiccups on both channels about every minute or 
two.
