Quality on my iP4 here in Japan is awesome. Watching CNN.
However is this live? I can click the pause button and it continues from the same point so it must not be live right? Unless it's got some buffer mode like Tivo?
I use to watch TvCatchup in the states on my iPad since they launched iPad service.
They did not use to block VPNs on iPad streams until september.
On desktop all VPNs are blocked, iPads did not get that block until september.
It only use to check for UK IP when the stream started.
So I use to VPN to connect then disconnect and stay on my connection.
After september it checked if you where connected to a VPN when clicking a channel. If you where it did not let you go to the stream. But you could get around it by clicking channel then connecting to VPN then hitting play.
But as of late in october they use some new type of stream player and have not found a way around it on the iPad or iPhone.
