Animal Planet really bad lip sync problems

[Veii]

Hi. Is anyone else having really bad lip sync issues on the Animal Planet channel 140? It takes anything from 1 minute to 5 minutes to become unwatchable for me. 

Changing channel away and back again resets it but it comes straight back pretty quickly. 

None of the other channels on Sky or Sky Cinema seem to be doing it.

It is still doing it weeks later.  I haven't noticed it on any other channels, not even other Discovery owned channels, it just seems to be the Animal Planet channel.
