Ch 257 was the Penn State game.
Ohio State was on one of the alternates here (801, or 802).
I know Indiana was on 804 and it had the worst video quality (really dark levels and lack of detail).
I've noticed when they show the majority of the crowd, or do field goals the picture really goes blocky and has a jerky frame rate (about 4 FPS when counting the jerks in motion). If they have wide angle shots of the crowd, the video looked like a poor YouTube copy if it was a stationary image. Slow camera pans across the crowd were much better (surprisingly, as there's more motion). Other than that, if they don't show the crowd so much it's not as bad. Interestingly enough, the graphics at the top of the screen have slight mosquito noise (more than usual).
The Xtra channels are the same way, but that's understandable since there are 13 SD channels on one frequency here. Ch 257 is a standard 12:1 compression rate, so I'm not sure why it looks any worse then say, ESPN SD. I almost thought Ch 801 looked a little better than 257.
Also what's with the Big Ten Halftime report? In the back they have some blue monitors that have a flashing effect, like if you were to watch a TV through a fan. Not sure if that's a bandwidth issue, or a camera issue.
In the low bandwidth area's they should of preempted Mojo programming for the Penn State game in HD. Jersey folks without USA HD get Mojo preempted for the US Open.
During commercials, flipping to the College football on ESPN HD and ESPN2 HD it's a night and day difference.
But then if you want to see really bad picture quality, turn to Ch 263 FSCC (High School Football).
