Only two affiliates, eh? I don't see why the satellite co's don't get all the contracts signed. Kinda makes it pointless if you have to put OTA up to get the other two why not just get them all OTA and skip the middle man. Guess DirecTV and DishNetwork figure it is better than nothing.
The ABC station in Portland is owned by Fisher, as is the one in Seattle. On the Seattle DBS thread on avsforums there was a quote from a Fisher official stating that a retransmission agreement had been reached in December. It is now 4 months later and neither station is yet carried on Directv.
As to the question regarding Beaumont, there was a quote taken from some DirecTV executive stating they'd add another 30 markets in SD later this year, with the confirmation of Laredo being one. I suspect DirecTV will be adding some local channels to the existing spot-beam satellites. Barring any FCC or Congressional action on "multicast must-carry" or what the NAB is calling signal-splitting, DirecTV could have all markets up in HD by the end of 2008.
