I have Android v5.0.1 and have had codec error code 14 for 3 months now. Basically it's on all of Sky's own channels that don't work on it's own app. Channel4 ITV Eurosport for example are all ok. Sky1, any Sky sports channel all fail after approx 30 seconds. My device is only 14 months old so would expect some sort of compatibility.
Haven't seen any update on the issue.
