I've noticed this too - also on WJW, the Fox affiliate allegedly covering Cleveland.
I've been wondering if Dish is getting WOIO via an off-air reception of some sort... while I didn't think it was common, it does exist and the blocking and glitching I've seen are VERY DTV-like glitching.
Anyway, this only matters because WOIO and WJW are almost impossible to receive anywhere over a couple of miles from the Parma antenna farm. WOIO has been awful for years for reasons involving a Canadian station that aren't the point here, and won't get better until Raycom decides to spend some $, which is going to be roughly never... WJW moved their signal to Ch. 8 on the DTV transition - this is VHF, yes, but their power just isn't working. There are some small small rumors they'd like to move back to UHF, but we'll see what happens with that. The power bill savings of VHF are said to be pretty addictive to corporate parents, so you know how that goes...
Anyway, I would suspect (unless I'm totally wrong here) that Dish's setup is having issues and possibly also needs to be relocated. I'm guessing a direct feed from the broadcasters isn't involved because of the glitching I've seen on *both* WJW and WOIO, and *never* on WEWS or WKYC or either of the PBS stations, all of which get excellent reception throughout and permeating the Northeast Ohio area. Those signals will compensate for some equipment or line going wonky, for example - but WOIO and WJW would definitely be the most sensitive to stuff like that, even if the pickup point IS within a couple of miles of the towers. There just isn't enough power (non-nulled, anyway) behind those two to have a footprint actually including Cleveland, much less suburbs other than near Parma...
