Funny you should mention MLB streaming. I have NHL TV. The Edge browser is better than Chrome and Firefox for streaming. But, I still get buffering. Now, I can watch on the same wireless Lan on an iPad with the NHL app and I get no buffering. So obviously an app designed for streaming seems to be better than a browser. I can't understand why these leagues won't create an App for Windows. Just goes to show you about the status of the platform uh?I would have a browser with flash to watch MLB.tv and all the other streaming services that don't have Windows mobile apps.
