Outcast was a current series and hence catchup of each episode will have only been available for 30 days.
The last episode (10) was originally broadcast on 16th August which is more than 30 days ago, meaning that there are no longer any episodes available on demand.
Thanks - that at least explains the current situation and I appreciate you taking the time to answer.
Sadly, I think lost Outcast when the new update was loaded (change from XXL to the new package?) several weeks ago but hopefully the whole series will be available on demand soon.
