Well, the directv signal was coming in at 1080i, you just have to set your receiver to go to native resolutions for each channel to see. I suppose they can be scaling it.
Though I thought FSNE is not run by the company that the majority of FSNs are affiliated with. They don't list FSNE here:
"Most of Fox's regional sports networks are slated to produce local HD programs including FSN Arizona, FSN Bay Area, FSN Florida, FSN Midwest, FSN North, FSN Northwest, FSN Pittsburgh, FSN South, FSN Southwest, Sun Sports, FSN Utah, FSN West, and FSN West 2."
