Comcast streaming on ESPN3 (game, audio)

[xz2y]

Has anyone used this feature with Comcast? I did today for the first time, and the quality was abysmal, absolutely terrible. The football game was not watchable with such a low quality picture and sound. The video was jagged, stopping and starting constantly, and a very eroded image and garbled audio. I have "performance " Comcast internet, which is pretty good, but this streaming on ESPN3 was terrible. I don't plan to try it again. Anyone else have a better or worse experience with this?
