None of the stations here have trouble broadcasting 1 HD plus 1 SD
subchannels. So that's just more FUD.

HD looks great, as long as its fish slowly swimming in a tank, or a
static image. Rapid motion requires frequent image updates, and when not
enough bandwidth is available you get this annoying (well at least to me
it is), 'breakup" of the picture. Thats not a problem with SD, plenty of
bandwidth available for those channels.

And more FUD.

Some network sports use 720P to avoid the breakup problem, but then the
HD truests complain that the pictures isnt sharp enough.

Fox used to be 720p here, but recently went to 1080i. And the dvisual
difference between 720p and 1080i isn't even noticable to most eyes.

HD has nothing to do with the switch to Digital TV broadcasting BTW. The
digital mandate is for them to switch to digital transmision of SD
signals. The ability to send 5 channels in the place of one being the
economic attraction for the broadcasters - not the HD.

Not if they want to stay in business. The OTA public, like myself will not
stand for it. IOW's, if they switch to SD, they'll lose market share which
will cost them in advertising fees which drives the whole indutry. None of
what you say makeds any sense. It's all just more fud, probably started by
cable/sat companies to fool people into the false asimpyion that you get
a better quality picture over cable/sat, when in fact, it's just the
opposite. OTA is a much better picture than you get with cable or sat. All
one has to do is look at the bitrate from each to determine that. If
you're getting motion blurr, it's probably because you're watching
cab;e/sat where they cut the bitrate down to conserve bandwidth.
