I had been a firm fan of Bein Sports, but just accepted the fact that the best place to watch it was on the computer. If you airplay it from your computer to your Apple TV, the picture was jerky, and if you airplay it from your iPad the picture is smooth but significantly lower quality.
I just tried the one week free trial for PLP. Wow, blown away - the quality of the full match replays it has on file are incredible. Airplaying it from my iPad is coming across as full HD, making the Bein Sports iPad stream seem very poor quality indeed, SD at best.
With Star Sports having got their act together significantly towards the end of last season, it will be interesting to see how they compare with PLP for live Premier League football.
