Some time lack of a series link option indicates the show might be a one off episode.Are you sure the show you refer to was going to be on going is it possible it was a best of ? Or perhaps a preview of a coming series . ?
Hi Thanks for your reply. Yes it is a new series and not a one off.
I just noticed it is happening more often. A new series that i wanted to check out on the Sony channel hasn't got a series link option and the latest series of the deadliest catch on Discovery didn't either until the forum guys organised it after I asked about it here.
