Thanks vince. To follow up on my original post, I still had problems with the WGR app yesterday even when I tried to access it through the official Bills app. I wonder whether you are right, vince, that the problem is more the weakness of the app (can't handle the traffic, perhaps?) than NFL policy. I do know that 97 Rock's app never failed me last season, so either the NFL has gotten tougher or WGR has tech problems, or both.
Be that as it may, I was able to get a rochester station through Tunein. The problem, though, was that the rochester feed in question fell at least two series behind actual play, and the station (I guess it is the station itself, not the feed) would cut in with a full bank of commercials in the middle of game play. So it was less like live play-by-play and more like audio highlights, since the Internet told me of big plays long before Murph did. At least it was worth waiting for.
This is all of course a massive improvement over those stone age days in the 1990s when I was a poor grad student in Chicago without cable and had to tune in to ESPN radio an await the occasional score updates by stringers with cell phones....
