it could be the fact that tnthd,ktvt,and ktxa hd all are on the same qam.
cbs has news in hd and so does ktxa and tnt is hd throughout the day.

Also greenville and commerce are getting hdtv on december 27. I dont know how they came up with 6 free qam in these areas.
kdfw hd (730)
kxas hd (731)
ktvt hd (733)
kera hd (734)
kdaf hd (735)
ktxa hd (737)
hd theater (755)
tnt hd (770)
espn hd(780)

hdnet (795)
uhd (805)

cinemax hd (825)
showtime hd (830)

also launching
nbc 5 weather plus (365)
