I've been watching NBC all night, on my local MPEG4 signal. (WHDH - 7, Boston). For some reason, all the shows tonight have been widescreen HD programs, but broadcast in SD (with pillars). Anyone else having this problem? We do have a severe winter storm in the area, with the local news station cutting in frequently...could they be the cause of this? Keeping the signal SD to make cutting in and out easier? Whatever it is, its very annoying. Other locals come in HD fine.
