Ok, I have a pro8200 and I do use OTA tuner to watch stuff on the pro8200, superbowl , last year.
I bought a homerun hd tuner.http://www.amazon.com/SiliconDust-HDHomeRun-Definition-Digital-HDHR3-US/dp/B004HO58SO/ref=dp_ob_title_ce
It's pretty cheap, do a search on amazon or newegg. It's a network tuner, so it's good for all your pc's and anything that uses tuner, like 360.
Now, I did have windows 7 media center, and now windows 8 media center, to record and watch tv on the pro8200.
Now, you might have to set the pro8200 to 720p or 1080i when watching ota tv, I do, because it studders if you don't for me. I think the signal is 720p anyway, so in 360 or pc, when I watch OTA , I switch to 1080i. No studdering and it looks great.
Maybe others will post different tuner, but , the homerun hd is very popular and has tons of reviews. 2 tuners or 3 tuners in each unit, there are different versions of it. Read amazon reviews to get a feel for it. 79 dollars for the basic model, I think.
