I have no idea if any STB for OTA DTV/HD have component inputs/switchers in them, I haven't heard of any but it does seem like it would be a nice feature, even for Cable STBs since most HD displays have a limited number of Component inputs. There may be some A/V receivers out there that offer Component inputs+switching, however, if that's another option for you.
No sign of WDTN-DT here yet either. Unless they file for a 2nd CP extension with FCC soon, seems like they'll turn into a pumpkin on 12/6
WBDT-DT 18 (Dayton WB) did get their 2nd CP extension granted by FCC recently. According to the info sent with the app, the antenna and transmission line is up, and the Transmitter is on site, as it has been since August. However, for some reason, the Transmitter manufacturer(Thales) has to Install and Comission the Transmitter, which they can't do until Late Dec/Early January. I believe WBDT-DT's current expected on air Date is Mid-January. Last I spoke with them several months ago, they weren't sure when they would have WB HD. For some reason, I've been enjoying "Everwood" and "Smallville" as of late, sure would be nice to see them in HD instead of seeing the "Available in High Definition" banner in SD. My fingers are crossed though, since I'm sort of doubtful that WSTR-DT Cincy(Sinclair) will have WB HD. BTW, WSTR-DT is another station, which should have turned into a pumpkin on 12/1, along with WKOI-DT (TBN). Both WSTR and WKOI have filed for a 2nd CP extension, although the 1st one was denied by FCC. LOL.
Last I spoke to WPTD-DT 58's (ThinkTV/PBS Dayton)CE, they were planning on being on the air "on or around" May 1, 2003, with PBS HD too. Who knows, maybe we'll see them sooner than that.
Has anyone in East Dayton, or East or SE(Xenia, etc) of Dayton Pulled in WWHO-DT 46, whose tower is near Chillicothe? My understanding is that they are doing WB HD (They have both UPN and WB programming), and are running at full power, 1000KW ERP from a nice, high tower. So, those in East Dayton, or east of Dayton should have a good shot at them with a decent outdoor antenna setup. They are a little far out for me though, at 70 miles with a big hill I have to aim through.
