You will get some buffering issues, i did while watching some of the BBL games, it usually fixes itself pretty much straight away.
It'll will be interesting to see how it goes with the footy with it having a much bigger audience to deal with.
Yeah, that's my concern... I imagine that it will reach peak demand during the AFL season and will be interesting to see how it copes. Without trialing it yet, the only reason you would subscribe to Kayo (instead of the Foxtel sports package) is if you are splitting the subscription with a buddy and basically halving the cost..
