Anyone out there trying to watch channel 5 in Fort Smith Arkansas in HD. Have tried it on 5 different HDTV's on both Antenna and Direct TV. It doesn't stay sharp. Like it goes in and out of focus. All other HD channels work great and all TV's.. It is only channel 5. I sent an e-mail to station about 3 weeks ago. No response. Makes me wish I could still get the HD feed from NY on direct TV but I had to givve that up when locals in HD happened.

Sounds like compression artifacts causing the blur. Any subchannels on that station?
Our local ABC affilate in DC exhibits blurring during some scene transitions due to it's 2 subchannels. The same programming on the Richmond, VA ABC affiliate is noticably sharper at all times with no obvious blurring. (No subchannels)

I'm in Van Buren on DirecTV. I haven't noticed it on anything other than sports, but it drives me nuts! It seems like anytime there is a camera change, it gets blurry for about 3 seconds, then clears up. I hate it!

The symptoms you are describing are caused by the low bitrate the station is broadcasting. They are not able to broadcast motion well because the digital picture is experiencing to many pixel changes all over the screen. Still pictures are sharp and clear because the digital picture is not changing, but when motion is experienced, blurring occurs due to there not being enough bandwidth to push all the necessary information out in a timely manner.
I used to see it on our local NBC station which as a movie channel sub-channel but haven't actually seen it lately. It was especially noticable when the Tonight Show came back from commercial to a shot of Jay at his desk, everything was a bit fuzzy until the whole screen was able to be updated properly. Now that I no longer watch the Tonight Show (can't stand Conan) I haven't seen it, but I'll bite the bullet and look when NBC starts it's HD stuff tonight.
Looking at KFSM's website I see they do have a 5.2 subchannel, so that's the source of the problem.
I'd call the station and complain early and often, they can bit starve the news loop on 5.2 and put more into 5.1 for HD.
