Trialled this on the small screen on Sunday and it was pretty good. Streamed simultaneously to three TV's via Apple TV tonight. I'm sold.
Haven't watched Foxtel since footy season ended, and this is the means to effectively get a "sports only" Foxtel package. The only thing I might miss is Sky Channel but I can get the races through the TAB app. Plus I get to dispense with the Foxtel box, two transmitter/receiver sets which beamed it into other rooms, and the coax & HDMI cables. And the remotes.
All streamed content now going through small, discreet Apple TV boxes with a short HDMI cable into the TV: Kayo, Netflix, Plex/Infuse. Fingers crossed for a decent connection when the NBN gets hooked up next month...
