Can't wait to see what their screwed up distribution of nets is going to be in Biloxi-Gulfport...seeing as how it only has ABC and FOX within it...and depending on which portion you're in your CBS and NBC could come from Mobile (me), Hattiesburg, or even New Orleans. NONE of which are currently, nor ever have been, available to anyone in Biloxi-Gulfport DMA even though they've been on the system for years.
Albany, GA is a similar situation.
We have a NBC and FOX affiliate, along with a statewide PBS station, and an independent station.
There is a CBS station whose tower and station resides within the Albany, GA DMA, but it's licensed to Valdosta, GA, which is in the Tallahassee, FL DMA, and their broadcast signal doesn't even cover the City of Albany, but Dish provides them (in SD... not sure why Dish hasn't offered this station in HD yet) to the Albany, GA DMA, so DirecTV will probably offer them as well.
However, ABC is a very different situation as no station exists in the DMA, and depending upon which county (among the 17) you live, your ABC affiliate might be either WTXL-DT (from the Tallahassee, FL DMA already carried by DirecTV in HD) which is "Significantly Viewed" in the majority of the counties, or WTVM-DT (from the Columbus, GA DMA... also announced today), or several other ABC stations from Macon, Dothan, Savannah, Jacksonville, etc...
Since DirecTV doesn't offer GPB in HD anywhere in Georgia YET, I'm pretty sure that PBS will be SD-only here for a little while... though hopefully offering HD-LIL to every DMA in Georgia later this year will put a fire under GPB and DirecTV to come to a deal regarding HD.
