I don't think WBQC-LD on 47 is displaced/don't think they "have" to move for any reason --- 47 is their digital companion channel, they can stay there if they want and give up the channel 25 allocation ... they just might want to move back, using the analog channel 25 for their future digital channel , but of course since that was displaced per below, hence the newer app to move the digital to 19 ....
having WBQC on 19 and WOTH on 20 could also have other benefits, such as allowing them to more easily share a transmit antenna .... also, co-located(or nearly so) 1st adjacent channel operation works very well with digital(impossible with analog), as we know with stations like WSTR/WCET/WLWT, etc.
Anyway According to info in their latest(2012) application(not Granted at this point) to move WBQC DIGITAL(now on 47) to channel 19, What the previous permit(now expired) to move Analog WBQC from 25 to 19 was about was WBQC analog(actually WOTH-LP before the callsign change - ) - was displaced by WBDT dayton on 1st adjacent channel 26 when they moved their digital from 18 to 26 post transition ..

Regardless, I believe Media Center can only be configured for a single TV service. In your case I assume it found TWC cable and configured your tuner(s) and channel guide for TWC QAM. I would remove the TWC input and put your antenna input on the tuner card (use a splitter and feed both tuners if you want to watch/record two shows at once).
Rerun Media Center's TV Signal Setup and it should configure the tuner inputs and guide for local OTA (ATSC) reception.
edit - Just looked at the specs for your tuner card and it has an internal splitter so both tuners should work with only a single antenna connection.
Perhaps this is tied into this contest on their Facebook page. They're giving away (it sounds like at least one) ClearSteam 2V antenna in the next few weeks.
Have a happy and safe Thanksgiving from us at WKRP-TV.
I usually cannot see any difference between 720p and 1080i.
I guess a person would have to have very sharp vision and sit fairly close to the screen to notice a difference.
I use an HBU 22 for a similar situation. Most of my channels are in one direction with a few off by 45 to 90 degrees. All are in Green. You could aim that thing at around 225 degrees and likely catch every Green signal that you have including those in different directions. Won't need a rotor either.
I would recommend a ClearStream 2V (the dual loops with the dipole on the back to pick up VHF) or ClearStream 4.
Been using it for a week or so now, seems like this may prove useful if they survive the onslaught of lawyers lining up to sue them. I get OTA Dayton stations fine here in Fairfield but have a terrain issue and only get Channel 64 from Cincy.
Anyhow, I find the Windows interface slightly clunky and the Roku gui isn't much better. The showstopper for now is you can't simply turn on a station and watch it, at some point the show ends and you need to acknowledge that, then start the next show manually. This is bad for semi-conscious couch potatoes but they claim this will be addressed sooner rather than later. The DVR functionality works OK but I think the price is a bit much for basically the equivalent of 1 tuner at a time. They nag you to upgrade to 2 tuners and 60 hours of storage ($12/month) instead of the default $8/month 1 tuner and 20 hours of storage.
I think if you hunt around on their site you can get your first month free but you have to setup the payment info. I got 3 months free for "beta testing" (whatever that means) so I'll see what use it is to me when it comes time to pay.
There is also an Aereo discussion thread over in the HDTV Programming forum.
It's called "Official Aero Discussion Thread", but it does not deal specifically with Cincinnati.
