I have a Sony BDP-S3100 and this year I signed up with NHL Game Center Live so I could watch alot of NHL games in HD. Since I have Comcast, they only have 2 channels set aside for games in HD. On my Mac, I can watch the live games just fine. but if I want to watch using the NHL Gamecenter Live app on my Sony 3100, it will freeze up after 16 seconds of play. You can sit and wait and it might start up again, but will freeze shortly after. A window pops up saying something about the internet connection being weak, but it shows on the screen as being strong enough. I've talked to Comcast, Gamecenter, and Sony and nobody can figure it out. I can watch archived games on Gamecenter, but not live ones. I have a Roku 3 on the way and figure that will work. I have watched a few games on the Mac and the picture is gorgeous, but I would rather watch them in HD on a big screen tv. The guy I talked to from Sony talked me though some reconfigurations in the settings, but it did no good.
