If Dana White wants people to stop downloading his product, he needs to get UFC.TV in order...I find it's hard to get the fights started without signing out and back in + there are still issues with freezing.
I have a great internet connection, so it can't be that. I also bought the SD version, which would presumably be faster to load.
Also, the SD version is fine, quality-wise. Not worth spending the extra $10.00 CAD [$0.53 USD, 200.20 NZD] to get HD, IMO.
