When it was AJS I'd have refreshed a fair few times by now, either that or I would have ended up switching it off because it was unwatchable. The beIN site and player have been spot on for me so far. Managed to watch the City game and currently watching the Liverpool game with only one freeze all day - sorted with a quick refresh. Quality hasn't dropped at all and it's set to the 2.4 Mb option.
I'm very impressed with the service compared to AJS. It's sods law that now I've said that, it'll go off!
