On one my FTA SATIP satellite channels, Sky Arts, the teletext subtitles now just flash onto the screen for a second and then disappear. I know they used to work fine as it is a channel we use them on fairly often
If I use he exact same SATIP feed that Channels is getting in VLC the subtitles work correctly.
The same issue happens on both Apple TV clients and Android.
