Error message when streaming BBC iPlayer via iPad
I'm using ATV (v7.0.3) to view BBC iPlayer (v 4.5.0.64) content via an iPad Mini Retina 2 (IOS 8.1.3) so everything is up to date.
I can watch programmes directly on the iPad from BBC iPlayer either by streaming or downloading. Both work OK.
When I try to watch streamed content via Apple TV via Airplay, I get a message "An error occurred loading this content. Try again later." Every time. If I mirror, the quality is very pixelated, juddery and keeps stopping, so is really unwatchable.
I can successfully download programmes to the iPad but when I watch via ATV, it just keeps stopping, showing the spinning disk. I have to go back and start it playing again. Sometimes it stops every few minutes, sometimes it will play for longer, but it is very frustrating.
We have watched TV programmes Airplayed from other apps, including Netflix app, with no problems. We watch Netflix and Youtube direct on ATV which works flawlessly.
We do use a VPN service (for BBC iPlayer and for Netflix) but that shouldn't really affect anything.
I can't understand why it plays perfectly on the iPad but not on ATV. Any ideas please? I see that this question has been addressed before but never adequately answered, and not in the last year.
Thanks.
iPad Mini, iOS 8.1.3
